The sample was already annealed at about 898˚C. The sample were subjected to chemical analysis, hardness, tensile and metallographic tests. These tests were performed on as received annealed and heat treated samples. In the annealed condition the sample showed 0HRC. However, on tensile testing, in annealed condition the sample showed maximum elongation. The heat treatment is carried out in vacuum furnace within temperature range 980-1035°C. The quenching of samples was carried out using liquid nitrogen. After hardening, the samples were subjected to tempering, which was carried out in vacuum tempering furnace at a temperature of 220˚C. The hardened samples were subjected to hardness and tensile testing. In hardness testing, the samples showed maximum hardness values. In tensile testing the sample showed minimum elongation. The sample in annealed state showed coarse plates of martensite structure. Therefore, the studied steels can be used as biomaterials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomaterials" title="biomaterials">biomaterials</a>, <a href="https://publications.waset.org/abstracts/search?q=martensitic%20steel" title=" martensitic steel"> martensitic steel</a>, <a href="https://publications.waset.org/abstracts/search?q=microsrtucture" title=" microsrtucture"> microsrtucture</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20testing" title=" tensile testing"> tensile testing</a>, <a href="https://publications.waset.org/abstracts/search?q=hardening" title=" hardening"> hardening</a>, <a href="https://publications.waset.org/abstracts/search?q=tempering" title=" tempering"> tempering</a>, <a href="https://publications.waset.org/abstracts/search?q=bioinstrumentation" title=" bioinstrumentation"> bioinstrumentation</a> </p> <a href="https://publications.waset.org/abstracts/9072/characterization-of-martensitic-stainless-steel-japanese-grade-aisi-420a" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9072.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">277</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3950</span> Evaluating Mechanical Properties of CoNiCrAlY Coating from Miniature Specimen Testing at Elevated Temperature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20Wen">W.

Sun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> CoNiCrAlY alloys have been widely used as bond coats for thermal barrier coating (TBC) systems because of low cost, improved control of composition, and the feasibility to tailor the coatings microstructures. Coatings are in general very thin structures, and therefore it is impossible to characterize the mechanical responses of the materials via conventional mechanical testing methods. Due to this reason, miniature specimen testing methods, such as the small punch test technique, have been developed. This paper presents some of the recent research in evaluating the mechanical properties of the CoNiCrAlY coatings at room and high temperatures, through the use of small punch testing and the developed miniature specimen tensile testing, applicable to a range of temperature, to investigate the elastic-plastic and creep behavior as well as ductile-brittle transition temperature (DBTT) behavior. An inverse procedure was developed to derive the mechanical properties from such tests for the coating materials. A two-layer specimen test method is also described. The key findings include: 1) the temperature-dependent coating properties can be accurately determined by the miniature tensile testing within a wide range of temperature; 2) consistent DBTTs can be identified by both the SPT and miniature tensile tests (~ 650 °C); and 3) the FE SPT modelling has shown good capability of simulating the early local cracking. In general, the temperature-dependent material behaviors of the CoNiCrAlY coating has been effectively characterized using miniature specimen testing and inverse method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NiCoCrAlY%20coatings" title="NiCoCrAlY coatings">NiCoCrAlY coatings</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=DBTT" title=" DBTT"> DBTT</a>, <a href="https://publications.waset.org/abstracts/search?q=miniature%20specimen%20testing" title=" miniature specimen testing"> miniature specimen testing</a> </p> <a href="https://publications.waset.org/abstracts/104223/evaluating-mechanical-properties-of-conicraly-coating-from-miniature-specimen-testing-at-elevated-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104223.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">169</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3949</span> Influence of Magnetized Water on the Split Tensile Strength of Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Justine%20Cyril%20E.%20Nunag">Justine Cyril E.

Tolosa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Concrete has high compressive strength but a low-tension strength. The small tensile strength of concrete is regarded as its primary weakness, which is why it is typically reinforced with steel, a material that is resistant to tension. Even with steel, however, cracking can occur. In strengthening concrete, only a few researchers have modified the water to be used in a concrete mix. This study aims to compare the split tensile strength of normal structural concrete to concrete prepared with magnetic water and a quick setting admixture. In this context, magnetic water is defined as tap water that has undergone a magnetic process to become magnetized water. To test the hypothesis that magnetized concrete leads to higher split tensile strength, twenty concrete specimens were made. There were five groups, each with five samples, that were differentiated by the number of cycles (0, 50, 100, and 150). The data from the Universal Testing Machine's split tensile strength were then analyzed using various statistical models and tests to determine the significant effect of magnetized water. The result showed a moderate (+0.579) but still significant degree of correlation. The researchers also discovered that using magnetic water for 50 cycles did not result in a significant increase in the concrete's split tensile strength, which influenced the analysis of variance. These results suggest that a concrete mix containing magnetic water and a quick-setting admixture alters the typical split tensile strength of normal concrete. Magnetic water has a significant impact on concrete tensile strength. The hardness property of magnetic water influenced the split tensile strength of concrete. In addition, a higher number of cycles results in a strong water magnetism. The laboratory test results show that a higher cycle translates to a higher tensile strength. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hardness%20property" title="hardness property">hardness property</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20water" title=" magnetic water"> magnetic water</a>, <a href="https://publications.waset.org/abstracts/search?q=quick-setting%20admixture" title=" quick-setting admixture"> quick-setting admixture</a>, <a href="https://publications.waset.org/abstracts/search?q=split%20tensile%20strength" title=" split tensile strength"> split tensile strength</a>, <a href="https://publications.waset.org/abstracts/search?q=universal%20testing%20machine" title=" universal testing machine"> universal testing machine</a> </p> <a href="https://publications.waset.org/abstracts/146441/influence-of-magnetized-water-on-the-split-tensile-strength-of-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146441.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3948</span> Polyvinyl Alcohol Processed Templated Polyaniline Films: Preparation, Characterization and Assessment of Tensile Strength </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Subbalakshmi">J.

PANIs have advantages of chemical stability and high conductivity making their commercial applications quite attractive. However, to our knowledge, very little work has been reported on the tensile strength properties of templated PANIs processed with polyvinyl alcohol and also, detailed study has not been carried out. We have investigated the effect of small molecule and polymers as templates on PANI. Stable aqueous colloidal suspensions of trisodium citrate (TSC), poly(ethylenedioxythiophene)-polystyrene sulfonate (PEDOT-PSS), and polyethylene glycol (PEG) templated PANIs were prepared through chemical synthesis, processed with polyvinyl alcohol (PVA) and were fabricated into films by solution casting. Absorption and infra-red spectra were studied to gain insight into the possible molecular interactions. Surface morphology was studied through scanning electron microscope and optical microscope. Interestingly, tensile testing studies revealed least strain for pure PVA when compared to the blends of templated PANI. Furthermore, among the blends, TSC templated PANI possessed maximum elasticity. The ultimate tensile strength for PVA processed, PEG-templated PANI was found to be five times more than other blends considered in this study. We establish structure–property correlation with morphology, spectral characterization and tensile testing studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=surface%20morphology" title="surface morphology">surface morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=processed%20films" title=" processed films"> processed films</a>, <a href="https://publications.waset.org/abstracts/search?q=polyvinyl%20alcohol" title=" polyvinyl alcohol"> polyvinyl alcohol</a>, <a href="https://publications.waset.org/abstracts/search?q=templated%20polyanilines" title=" templated polyanilines"> templated polyanilines</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20testing" title=" tensile testing"> tensile testing</a> </p> <a href="https://publications.waset.org/abstracts/56229/polyvinyl-alcohol-processed-templated-polyaniline-films-preparation-characterization-and-assessment-of-tensile-strength" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56229.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">214</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3947</span> Experimental Characterization of Anisotropic Mechanical Properties of Textile Woven Fabric</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rym%20Zouari">Rym Zouari</a>, <a href="https://publications.waset.org/abstracts/search?q=Sami%20Ben%20Amar"> Sami Ben Amar</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelwaheb%20Dogui"> Abdelwaheb Dogui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an experimental characterization of the anisotropic mechanical behavior of 4 textile woven fabrics with different weaves (Twill 3, Plain, Twill4 and Satin 4) by off-axis tensile testing.

The fabrication processing parameters predominantly influence FDM part strength and mechanical properties. This presentation will demonstrate the influences of the two manufacturing parameters on the tensile testing evaluation indexes, infill density, and Printing Orientation, which were analyzed to create a piping spacer suitable for oil and gas applications. The tensile specimens are made of two polymers, Acrylonitrile Styrene Acrylate (ASA) and High high-impact polystyrene (HIPS), to characterize the mechanical properties performance for creating the final product. The mechanical testing was carried out per the ASTM D638 testing standard, following Type IV requirements. Taguchi's experiment design using an L-9 orthogonal array was used to evaluate the performance output and identify the optimal manufacturing factors. The experimental results demonstrate that the tensile test is more pronounced with 100% infill for ASA and HIPS samples. However, the printing orientations varied in reactions; ASA is maximum at 0 degrees while HIPS shows almost similar percentages between 45 and 90 degrees. Taguchi-Gray integrated methodology was adopted to minimize the response and recognize optimal fabrication factors combinations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FDM" title="FDM">FDM</a>, <a href="https://publications.waset.org/abstracts/search?q=ASTM%20D638" title=" ASTM D638"> ASTM D638</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20testing" title=" tensile testing"> tensile testing</a>, <a href="https://publications.waset.org/abstracts/search?q=acrylonitrile%20styrene%20acrylate" title=" acrylonitrile styrene acrylate"> acrylonitrile styrene acrylate</a> </p> <a href="https://publications.waset.org/abstracts/171454/additive-manufacturing-optimization-via-integrated-taguchi-gray-relation-methodology-for-oil-and-gas-component-fabrication" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171454.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">93</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3945</span> Study of Bolt Inclination in a Composite Single Bolted Joint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faci%20Youcef">Faci Youcef</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Mebtouche"> Ahmed Mebtouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Djillali%20Allou"> Djillali Allou</a>, <a href="https://publications.waset.org/abstracts/search?q=Maalem%20Badredine"> Maalem Badredine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The inclination of the bolt in a fastened joint of composite material during a tensile test can be influenced by several parameters, including material properties, bolt diameter and length, the type of composite material being used, the size and dimensions of the bolt, bolt preload, surface preparation, the design and configuration of the joint, and finally testing conditions.

It can cause stress concentrations and localized deformation in the material, leading to damage such as delamination, fiber breakage, matrix cracking, and other forms of failure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damage" title="damage">damage</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20image%20correlation" title=" digital image correlation"> digital image correlation</a>, <a href="https://publications.waset.org/abstracts/search?q=bolt%20inclination%20angle" title=" bolt inclination angle"> bolt inclination angle</a>, <a href="https://publications.waset.org/abstracts/search?q=joint" title=" joint"> joint</a> </p> <a href="https://publications.waset.org/abstracts/182322/an-experimental-study-of-bolt-inclination-in-a-composite-single-bolted-joint" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182322.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">68</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3943</span> Mechanical Characterization of Porcine Skin with the Finite Element Method Based Inverse Optimization Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Djamel%20Remache">Djamel Remache</a>, <a href="https://publications.waset.org/abstracts/search?q=Serge%20Dos%20Santos"> Serge Dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Cliez"> Michael Cliez</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Gratton"> Michel Gratton</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Chabrand"> Patrick Chabrand</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Marie%20Rossi"> Jean-Marie Rossi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Louis%20Milan"> Jean-Louis Milan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Skin tissue is an inhomogeneous and anisotropic material. Uniaxial tensile testing is one of the primary testing techniques for the mechanical characterization of skin at large scales. In order to predict the mechanical behavior of materials, the direct or inverse analytical approaches are often used. However, in case of an inhomogeneous and anisotropic material as skin tissue, analytical approaches are not able to provide solutions. The numerical simulation is thus necessary. In this work, the uniaxial tensile test and the FEM (finite element method) based inverse method were used to identify the anisotropic mechanical properties of porcine skin tissue. The uniaxial tensile experiments were performed using Instron 8800 tensile machine®. The uniaxial tensile test was simulated with FEM, and then the inverse optimization approach (or the inverse calibration) was used for the identification of mechanical properties of the samples. Experimentally results were compared to finite element solutions. The results showed that the finite element model predictions of the mechanical behavior of the tested skin samples were well correlated with experimental results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mechanical%20skin%20tissue%20behavior" title="mechanical skin tissue behavior">mechanical skin tissue behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=uniaxial%20tensile%20test" title=" uniaxial tensile test"> uniaxial tensile test</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=inverse%20optimization%20approach" title=" inverse optimization approach"> inverse optimization approach</a> </p> <a href="https://publications.waset.org/abstracts/65920/mechanical-characterization-of-porcine-skin-with-the-finite-element-method-based-inverse-optimization-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65920.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">408</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3942</span> Experimental Investigations on the Mechanical properties of Spiny (Kawayan Tinik) Bamboo Layers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ma.%20Doreen%20E.%20Candelaria">Ma.

Its potential use in the field of engineering, however, is still not widely practiced due to insufficient engineering knowledge on the material’s properties and characteristics. Although there are researches and studies proving its advantages, it is still not enough to say that bamboo can sustain and provide the strength and capacity required of common structures. In line with this, a more detailed analysis was made to observe the layered structure of the bamboo, particularly the species of Kawayan Tinik. It is the main intent of this research to provide the necessary experiments to determine the tensile strength of dried bamboo samples. The test includes tensile strength parallel to fibers with samples taken at internodes only. Throughout the experiment, methods suggested by the International Organization for Standardization (ISO) were followed. The specimens were tested using 3366 INSTRON Universal Testing Machine, with a rate of loading set to 0.6 mm/min. It was then observed from the results of these experiments that dried bamboo samples recorded high layered tensile strengths, as high as 600 MPa. Likewise, along the culm’s length and across its cross section, higher tensile strength were observed at the top part and at its outer layers. Overall, the top part recorded the highest tensile strength per layer, with its outer layers having tensile strength as high as 600 MPa. The recorded tensile strength of its middle and inner layers, on the other hand, were approximately 450 MPa and 180 MPa, respectively. From this variation in tensile strength across the cross section, it may be concluded that an increase in tensile strength may be observed towards the outer periphery of the bamboo. With these preliminary investigations on the layered tensile strength of bamboo, it is highly recommended to conduct experimental investigations on the layered compressive strength properties as well. It is also suggested to conduct investigations evaluating perpendicular layered tensile strength of the material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bamboo%20strength" title="bamboo strength">bamboo strength</a>, <a href="https://publications.waset.org/abstracts/search?q=layered%20strength%20tests" title=" layered strength tests"> layered strength tests</a>, <a href="https://publications.waset.org/abstracts/search?q=strength%20test" title=" strength test"> strength test</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20test" title=" tensile test "> tensile test </a> </p> <a href="https://publications.waset.org/abstracts/24458/experimental-investigations-on-the-mechanical-properties-of-spiny-kawayan-tinik-bamboo-layers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24458.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">418</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3941</span> Waterproofing Agent in Concrete for Tensile Improvement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhamad%20Azani%20Yahya">Muhamad Azani Yahya</a>, <a href="https://publications.waset.org/abstracts/search?q=Umi%20Nadiah%20Nor%20Ali"> Umi Nadiah Nor Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Alias%20Yusof"> Mohammed Alias Yusof</a>, <a href="https://publications.waset.org/abstracts/search?q=Norazman%20Mohamad%20Nor"> Norazman Mohamad Nor</a>, <a href="https://publications.waset.org/abstracts/search?q=Vikneswaran%20Munikanan"> Vikneswaran Munikanan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In construction, concrete is one of the materials that can commonly be used as for structural elements. Concrete consists of cement, sand, aggregate and water. Concrete can be added with admixture in the wet condition to suit the design purpose such as to prolong the setting time to improve workability. For strength improvement, concrete is being added with other hybrid materials to increase strength; this is because the tensile strength of concrete is very low in comparison to the compressive strength. This paper shows the usage of a waterproofing agent in concrete to enhance the tensile strength. High tensile concrete is expensive because the concrete mix needs fiber and also high cement content to be incorporated in the mix. High tensile concrete being used for structures that are being imposed by high impact dynamic load such as blast loading that hit the structure. High tensile concrete can be defined as a concrete mix design that achieved 30%-40% tensile strength compared to its compression strength. This research evaluates the usage of a waterproofing agent in a concrete mix as an element of reinforcement to enhance the tensile strength. According to the compression and tensile test, it shows that the concrete mix with a waterproofing agent enhanced the mechanical properties of the concrete. It is also show that the composite concrete with waterproofing is a high tensile concrete; this is because of the tensile is between 30% and 40% of the compression strength. This mix is economical because it can produce high tensile concrete with low cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20tensile%20concrete" title="high tensile concrete">high tensile concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=waterproofing%20agent" title=" waterproofing agent"> waterproofing agent</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete" title=" concrete"> concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=rheology" title=" rheology"> rheology</a> </p> <a href="https://publications.waset.org/abstracts/58331/waterproofing-agent-in-concrete-for-tensile-improvement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58331.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">327</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3940</span> Estimation of Tensile Strength for Granitic Rocks by Using Discrete Element Approach </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aliakbar%20Golshani">Aliakbar Golshani</a>, <a href="https://publications.waset.org/abstracts/search?q=Armin%20Ramezanzad"> Armin Ramezanzad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tensile strength which is an important parameter of the rock for engineering applications is difficult to measure directly through physical experiment (i.e. uniaxial tensile test).

In this research, to calculate numerically the tensile strength for granitic rocks, Particle Flow Code in three-dimension (PFC3D) software were used. First, uniaxial compression tests were simulated and the tensile strength was determined for Inada granite (from a quarry in Kasama, Ibaraki, Japan). Then, by simulating Brazilian test condition for Inada granite, the tensile strength was indirectly calculated again.

It is composed to bring a revolution in the way products are designed, planned, manufactured, and distributed to end users. Fused deposition modeling (FDM) based 3D printing is one of those promising aspects that have revolutionized the prototyping processes. The purpose of this design and study project is to design a customized laboratory-scale FDM-based 3D printer from locally available sources. The primary goal is to design and fabricate the FDM-based 3D printer. After the fabrication, a tensile test specimen would be designed in Solid Works or [Creo computer-aided design (CAD)] software. A .stl file is generated of the tensile test specimen through slicing software and the G-codes are inserted via a computer for the test specimen to be printed. Different parameters were under studies like printing speed, layer thickness and infill density of the printed object. Some parameters were kept constant such as temperature, extrusion rate, raster orientation etc. Different tensile test specimens were printed for a different sets of parameters of the FDM-based 3d printer. The tensile test specimen were subjected to tensile tests using a universal testing machine (UTM). Design Expert software has been used for analyses, So Different results were obtained from the different tensile test specimens. The best, average and worst specimen were also observed under a compound microscope to investigate the layer bonding in between. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing%20techniques" title="additive manufacturing techniques">additive manufacturing techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20printing" title=" 3D printing"> 3D printing</a>, <a href="https://publications.waset.org/abstracts/search?q=CAD%20software" title=" CAD software"> CAD software</a>, <a href="https://publications.waset.org/abstracts/search?q=UTM%20machine" title=" UTM machine"> UTM machine</a> </p> <a href="https://publications.waset.org/abstracts/158329/investigation-of-the-effects-of-processing-parameters-on-pla-based-3d-printed-tensile-samples" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158329.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">103</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3938</span> Effect of Saturation and Deformation Rate on Split Tensile Strength for Various Sedimentary Rocks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20K.%20Soni">D.

The laboratory test results on equally dimensioned discs of the stone show a considerable variation in computed split tensile strength with varied rates of deformation. Hence, the effect of strain rate on the tensile strength of a sand stone and lime stone under wet and dry conditions has been studied experimentally using the split tensile strength test technique. It has been observed that the tensile strength of these stone is very much dependent on the rate of deformation particularly in a dry state. On saturation the value of split tensile strength reduced considerably depending upon the structure of rock and amount of water absorption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sedimentary%20rocks" title="sedimentary rocks">sedimentary rocks</a>, <a href="https://publications.waset.org/abstracts/search?q=split%20tensile%20test" title=" split tensile test"> split tensile test</a>, <a href="https://publications.waset.org/abstracts/search?q=deformation%20rate" title=" deformation rate"> deformation rate</a>, <a href="https://publications.waset.org/abstracts/search?q=saturation%20rate" title=" saturation rate"> saturation rate</a>, <a href="https://publications.waset.org/abstracts/search?q=sand%20stone" title=" sand stone"> sand stone</a>, <a href="https://publications.waset.org/abstracts/search?q=lime%20stone" title=" lime stone"> lime stone</a> </p> <a href="https://publications.waset.org/abstracts/7251/effect-of-saturation-and-deformation-rate-on-split-tensile-strength-for-various-sedimentary-rocks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7251.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">409</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3937</span> Analyses of Uniaxial and Biaxial Flexure Tests Used in Ceramic Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Barry%20Hojjatie">Barry Hojjatie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Uniaxial (e.g., three-point bending) and biaxial flexure tests are used frequently for determining the strength of ceramics. It is generally believed that the biaxial test has an advantage as compared to uniaxial test because it produces a state of pure tension on the lower surface of the specimen and the maximum tensile stress, which is usually responsible for crack initiation and failure is unaffected by the edge condition. However, inconsistent strength values have been reported for the same material and testing conditions. The objective of this study was to analyze the strength of dental porcelain materials using the two different test methods and evaluate the main contributions to variability in biaxial testing and to analyze the relative influence of variables such as specimen geometric conditions and loading conditions on calculated strength of porcelain subjected to biaxial testing. Porcelain disks (16 mm dia x 2 mm thick) were subjected to biaxial flexure (pin-on-three-ball), and flexure strength values were calculated. A 3-D finite element model was developed to simulate various biaxial flexure test conditions. Stresses were analyzed for ceramic thickness in the range of 1.0-3.0 mm. For a 2-mm-thick disk subjected to a point load of 200 N, the maximum tensile stress at the lower surface was 180 MPa. This stress decreased to 95, 77, 68, and 59 MPa for the radius of the load values of 0.15, 0.3, 0.6, and 1.0 mm, respectively. Tensile stresses which developed at the top surface near the site of loading were small for the radius of the load ≥ 0.6 mm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ceramis" title="ceramis">ceramis</a>, <a href="https://publications.waset.org/abstracts/search?q=biaxial" title=" biaxial"> biaxial</a>, <a href="https://publications.waset.org/abstracts/search?q=flexure%20test" title=" flexure test"> flexure test</a>, <a href="https://publications.waset.org/abstracts/search?q=uniaxial" title=" uniaxial"> uniaxial</a> </p> <a href="https://publications.waset.org/abstracts/106029/analyses-of-uniaxial-and-biaxial-flexure-tests-used-in-ceramic-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106029.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3936</span> Development of Impressive Tensile Properties of Hybrid Rolled Ta0.5Nb0.5Hf0.5ZrTi1.5 Refractory High Entropy Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Veeresham">M.

Parts fabricated using FDM process have mechanical properties comparable with those of injection-molded parts. However, performance of the FDM part is severally affected by the poor mechanical properties of the part due to nature of layered structure of printed part. Mechanical properties of the part can be improved by proper selection of process variables. In the present study, a comparative study between unidirectional and bidirectional raster angle has been carried out at a combination of different layer height and raster width. Unidirectional raster angle varied at five different levels, and bidirectional raster angle has been varied at three different levels. Fabrication of tensile specimen and tensile testing of specimen has been conducted according to ASTM D638 standard. From the results, it can be observed that higher tensile strength has been obtained at 0° raster angle followed by 45°/45° raster angle, while lower tensile strength has been obtained at 90° raster angle. Analysis of fractured surface revealed that failure takes place along with raster deposition direction for unidirectional and zigzag failure can be observed for bidirectional raster angle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title="additive manufacturing">additive manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=fused%20deposition%20modeling" title=" fused deposition modeling"> fused deposition modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=unidirectional" title=" unidirectional"> unidirectional</a>, <a href="https://publications.waset.org/abstracts/search?q=bidirectional" title=" bidirectional"> bidirectional</a>, <a href="https://publications.waset.org/abstracts/search?q=raster%20angle" title=" raster angle"> raster angle</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20strength" title=" tensile strength"> tensile strength</a> </p> <a href="https://publications.waset.org/abstracts/86885/tensile-properties-of-3d-printed-pla-under-unidirectional-and-bidirectional-raster-angle-a-comparative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86885.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">185</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3934</span> Simulation and Experimental Study on Tensile Force Measurement of PS Tendons Using an Embedded EM Sensor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=ByoungJoon%20Yu">ByoungJoon Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Junkyeong%20Kim"> Junkyeong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Seunghee%20Park"> Seunghee Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The tensile force estimation PS tendons is in great demand on monitoring the structural health condition of PSC girder bridges.

The permeability is changed due to the induced tensile force by the magneto-elastic effect and the effect then lead to the gradient change of the B-H curve. An experiment was performed to obtain the signals from the EM sensor using three down-scaled PSC girder models. The permeability of PS tendons was proportionally decreased according to the increase of the tensile forces. To verify the experiment results, a simulation of tensile force estimation will be conducted in further study. Consequently, it is expected that both the experiment results and the simulation results increase the accuracy of the tensile force estimation, and then it could be one of the solutions for evaluating the performance of PSC girder. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tensile%20force%20estimation" title="tensile force estimation">tensile force estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=embedded%20EM%20sensor" title=" embedded EM sensor"> embedded EM sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=PSC%20girder" title=" PSC girder"> PSC girder</a>, <a href="https://publications.waset.org/abstracts/search?q=EM%20sensor%20simulation" title=" EM sensor simulation"> EM sensor simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=cross%20section%20loss" title=" cross section loss"> cross section loss</a> </p> <a href="https://publications.waset.org/abstracts/57263/simulation-and-experimental-study-on-tensile-force-measurement-of-ps-tendons-using-an-embedded-em-sensor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57263.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">479</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3933</span> Evaluation of Mechanical Properties of Welds Fabricated at a Close Proximity on Offshore Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Nakkeran">T.

The experiment was designed using welded S355 D Z35 with distances between two parallel adjacent weld toes at 8 mm. These distances were less than the distance that has normally been recommended in standards, codes, and specifications. The main idea of the analysis is to determine any significant effects when welding the joints with the close proximity of 8mm using the SAW welding process of the one joint with high heat put and one joint welded with the FCAW welding process and evaluating the destructing and nondestructive testing between the welded joints. Further, we have evaluated the joints with Mechanical Testing for evaluating by performing Tensile test, bend testing, Macrostructure, Microstructure, Hardness test, and Impact testing. After evaluating the final outcome of the result, no significant changes were observed for welding the close proximity of weld of 8mm distance between the joints as compared to the specification minimum distance between the weldments of any design should be 50mm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=S355%20carbon%20steel" title="S355 carbon steel">S355 carbon steel</a>, <a href="https://publications.waset.org/abstracts/search?q=weld%20proximity" title=" weld proximity"> weld proximity</a>, <a href="https://publications.waset.org/abstracts/search?q=SAW%20process" title=" SAW process"> SAW process</a>, <a href="https://publications.waset.org/abstracts/search?q=FCAW%20process" title=" FCAW process"> FCAW process</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20input" title=" heat input"> heat input</a>, <a href="https://publications.waset.org/abstracts/search?q=bend%20test" title=" bend test"> bend test</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20test" title=" tensile test"> tensile test</a>, <a href="https://publications.waset.org/abstracts/search?q=hardness%20test" title=" hardness test"> hardness test</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20test" title=" impact test"> impact test</a>, <a href="https://publications.waset.org/abstracts/search?q=macro%20and%20microscopic%20examinations" title=" macro and microscopic examinations"> macro and microscopic examinations</a> </p> <a href="https://publications.waset.org/abstracts/155282/evaluation-of-mechanical-properties-of-welds-fabricated-at-a-close-proximity-on-offshore-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155282.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">98</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3932</span> Effect of Confinement on Flexural Tensile Strength of Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Ahmed">M.

Many factors have been shown to influence the flexural tensile strength, particularly the level of concrete strength, size of member, age of concrete and confinement to flexure member etc. Empirical equations have been suggested to relate the flexural tensile strength and compressive strength. Limited literature is available for relationship between flexural tensile strength and compressive strength giving consideration to the factors affecting the flexural tensile strength specially the concrete confinement factor. The concrete member such as slabs, beams and columns critical locations are under confinement effects. The paper presents the experimental study to predict the flexural tensile strength and compressive strength empirical relations using statistical procedures considering the effect of confinement and age of concrete for wide range of concrete strength (from 35 to about 100 MPa). It is concluded from study that due consideration of confinement should be given in deriving the flexural tensile strength and compressive strength proportionality equations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title="compressive strength">compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=flexural%20tensile%20strength" title=" flexural tensile strength"> flexural tensile strength</a>, <a href="https://publications.waset.org/abstracts/search?q=modulus%20of%20rupture" title=" modulus of rupture"> modulus of rupture</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20procedures" title=" statistical procedures"> statistical procedures</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete%20confinement" title=" concrete confinement"> concrete confinement</a> </p> <a href="https://publications.waset.org/abstracts/2078/effect-of-confinement-on-flexural-tensile-strength-of-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2078.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">457</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3931</span> Automated Java Testing: JUnit versus AspectJ</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manish%20Jain">Manish Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Dinesh%20Gopalani"> Dinesh Gopalani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Growing dependency of mankind on software technology increases the need for thorough testing of the software applications and automated testing techniques that support testing activities.

Likewise JUnit, a unit testing framework is the most popular Java testing tool. In this paper, we have evaluated our proposed AOP approach for automated testing and JUnit on various parameters. First we have provided the similarity between the two approaches and then we have done a detailed comparison of the two testing techniques on factors like lines of testing code, learning curve, testing of private members etc. We established that our AOP testing approach using AspectJ has got several advantages and is thus particularly more effective than JUnit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aspect%20oriented%20programming" title="aspect oriented programming">aspect oriented programming</a>, <a href="https://publications.waset.org/abstracts/search?q=AspectJ" title=" AspectJ"> AspectJ</a>, <a href="https://publications.waset.org/abstracts/search?q=aspects" title=" aspects"> aspects</a>, <a href="https://publications.waset.org/abstracts/search?q=JU-nit" title=" JU-nit"> JU-nit</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20testing" title=" software testing"> software testing</a> </p> <a href="https://publications.waset.org/abstracts/82341/automated-java-testing-junit-versus-aspectj" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82341.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">331</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3930</span> Tensile Force Estimation for Real-Size Pre-Stressed Concrete Girder using Embedded Elasto-Magnetic Sensor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Junkyeong%20Kim">Junkyeong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jooyoung%20Park"> Jooyoung Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Aoqi%20Zhang"> Aoqi Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Seunghee%20Park"> Seunghee Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The tensile force of Pre-Stressed Concrete (PSC) girder is the most important factor for evaluating the performance of PSC girder bridges. To measure the tensile force of PSC girder, several NDT methods were studied. However, conventional NDT method cannot be applied to the real-size PSC girder because the PS tendons could not be approached. To measure the tensile force of real-size PSC girder, this study proposed embedded EM sensor based tensile force estimation method. The embedded EM sensor could be installed inside of PSC girder as a sheath joint before the concrete casting. After curing process, the PS tendons were installed, and the tensile force was induced step by step using hydraulic jacking machine. The B-H loop was measured using embedded EM sensor at each tensile force steps and to compare with actual tensile force, the load cell was installed at each end of girder. The magnetization energy loss, that is the closed area of B-H loop, was decreased according to the increase of tensile force with regular pattern. Thus, the tensile force could be estimated by the tracking the change of magnetization energy loss of PS tendons. Through the experimental result, the proposed method can be used to estimate the tensile force of the in-situ real-size PSC girder bridge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tensile%20force%20estimation" title="tensile force estimation">tensile force estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=embedded%20EM%20sensor" title=" embedded EM sensor"> embedded EM sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetization%20energy%20loss" title=" magnetization energy loss"> magnetization energy loss</a>, <a href="https://publications.waset.org/abstracts/search?q=PSC%20girder" title=" PSC girder"> PSC girder</a> </p> <a href="https://publications.waset.org/abstracts/57237/tensile-force-estimation-for-real-size-pre-stressed-concrete-girder-using-embedded-elasto-magnetic-sensor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57237.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">337</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3929</span> Comparison of Direct and Indirect Tensile Strength of Brittle Materials and Accurate Estimate of Tensile Strength</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Etezadi">M.

The difficulties associated with performing a direct uniaxial tensile test on a rock specimen have led to a number of indirect methods for assessing the tensile strength that in the meantime the Brazilian test is more popular. Brazilian test is widely applied in rock engineering because specimens are easy to prepare, the test is easy to conduct and uniaxial compression test machines are quite common. This study compares experimental results of direct and Brazilian tensile tests carried out on two rock types and three concrete types using 39 cylindrical and 28 disc specimens. The tests are performed using Servo-Control device. The relationship between direct and indirect tensile strength of specimens is extracted using linear regression. In the following, tensile strength of direct and indirect test is evaluated using finite element analysis. The results are analyzed and effective factors on results are studied. According to the experimental results Brazilian test is shown higher tensile strength than direct test. Because of decreasing the contact surface of grains and increasing the uniformity in concrete specimens with fine aggregate (largest grain size= 6mm), higher tensile strength in direct test is shown. The experimental and numerical results of tensile strength are compared and empirical relationship witch is obtained from experimental tests is validated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tensile%20strength" title="tensile strength">tensile strength</a>, <a href="https://publications.waset.org/abstracts/search?q=brittle%20materials" title=" brittle materials"> brittle materials</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20and%20indirect%20tensile%20test" title=" direct and indirect tensile test"> direct and indirect tensile test</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20modeling" title=" numerical modeling "> numerical modeling </a> </p> <a href="https://publications.waset.org/abstracts/36005/comparison-of-direct-and-indirect-tensile-strength-of-brittle-materials-and-accurate-estimate-of-tensile-strength" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36005.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">546</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3928</span> An Integrated Approach to Find the Effect of Strain Rate on Ultimate Tensile Strength of Randomly Oriented Short Glass Fiber Composite in Combination with Artificial Neural Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sharad%20Shrivastava">Sharad Shrivastava</a>, <a href="https://publications.waset.org/abstracts/search?q=Arun%20Jalan"> Arun Jalan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study tensile testing was performed on randomly oriented short glass fiber/epoxy resin composite specimens which were prepared using hand lay-up method.

Using crushed waste glass in hot mix asphalt paving has been though as an alternative to landfill disposal and recycling. This paper discusses the possibility of utilizing crushed waste glass, as a part of fine aggregate in hot mix asphalt in Egypt. This is done through evaluation of the mechanical properties of asphalt concrete mixtures mixed with waste glass and determining the appropriate glass content that can be adapted in asphalt pavement. Four asphalt concrete mixtures with various glass contents, namely; 0%, 4%, 8% and 12% by weight of total mixture were studied. Evaluation of the mechanical properties includes performing Marshall stability, indirect tensile strength, fracture energy and unconfined compressive strength tests. Laboratory testing had revealed the enhancement in both compressive strength and Marshall stability test parameters when the crushed glass was added to asphalt concrete mixtures. This enhancement was accompanied with a very slight reduction in both indirect tensile strength and fracture energy when glass content up to 8% was used. Adding more than 8% of glass causes a sharp reduction in both indirect tensile strength and fracture energy. Testing results had also shown a reduction in the optimum asphalt content when the waste glass was used. Measurements of the heat loss rate of asphalt concrete mixtures mixed with glass revealed their ability to hold heat longer than conventional mixtures. This can have useful application in asphalt paving during cold whether or when a long period of post-mix transportation is needed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=waste%20glass" title="waste glass">waste glass</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20mix%20asphalt" title=" hot mix asphalt"> hot mix asphalt</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20performance" title=" mechanical performance"> mechanical performance</a>, <a href="https://publications.waset.org/abstracts/search?q=indirect%20tensile%20strength" title=" indirect tensile strength"> indirect tensile strength</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture%20energy" title=" fracture energy"> fracture energy</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a> </p> <a href="https://publications.waset.org/abstracts/56958/investigation-of-the-mechanical-performance-of-hot-mix-asphalt-modified-with-crushed-waste-glass" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56958.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">310</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3926</span> Effect of Welding Processes on Tensile Behavior of Aluminum Alloy Joints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chaitanya%20Sharma">Chaitanya Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Vikas%20Upadhyay"> Vikas Upadhyay</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Tripathi"> A.

After HRDSR, both the recovery stress and strain were enhanced compared to the initial condition. The constitutive equation showing that the maximum recovery stress is a sole function of the recovery strain was developed based on the experimental data. The recovery strain increased as the yield stress increased. The maximum recovery stress increased with an increase in yield stress. The residual recovery stress was affected by the yield stress as well as the austenite-to-martensite transformation temperature. As the yield stress increased and as the martensitic transformation temperature decreased, the residual recovery stress increased. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-ratio%20differential%20speed%20rolling" title="high-ratio differential speed rolling">high-ratio differential speed rolling</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20testing" title=" tensile testing"> tensile testing</a>, <a href="https://publications.waset.org/abstracts/search?q=severe%20plastic%20deformation" title=" severe plastic deformation"> severe plastic deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=shape%20memory%20alloys" title=" shape memory alloys"> shape memory alloys</a> </p> <a href="https://publications.waset.org/abstracts/69337/measurements-of-recovery-stress-and-recovery-strain-of-ni-based-shape-memory-alloys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69337.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">366</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3923</span> Estimation of Physico-Mechanical Properties of Tuffs (Turkey) from Indirect Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Gok">Mustafa Gok</a>, <a href="https://publications.waset.org/abstracts/search?q=Sair%20Kahraman"> Sair Kahraman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Fener"> Mustafa Fener</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In rock engineering applications, determining uniaxial compressive strength (UCS), Brazilian tensile strength (BTS), and basic index properties such as density, porosity, and water absorption is crucial for the design of both underground and surface structures. However, obtaining reliable samples for direct testing, especially from rocks that weather quickly and have low strength, is often challenging. In such cases, indirect methods provide a practical alternative to estimate the physical and mechanical properties of these rocks. In this study, tuff samples collected from the Cappadocia region (Nevşehir) in Turkey were subjected to indirect testing methods. Over 100 tests were conducted, using needle penetrometer index (NPI), point load strength index (PLI), and disc shear index (BPI) to estimate the uniaxial compressive strength (UCS), Brazilian tensile strength (BTS), density, and water absorption index of the tuffs. The relationships between the results of these indirect tests and the target physical properties were evaluated using simple and multiple regression analyses. The findings of this research reveal strong correlations between the indirect methods and the mechanical properties of the tuffs. Both uniaxial compressive strength and Brazilian tensile strength could be accurately predicted using NPI, PLI, and BPI values. The regression models developed in this study allow for rapid, cost-effective assessments of tuff strength in cases where direct testing is impractical. These results are particularly valuable for geological engineering applications, where time and resource constraints exist. This study highlights the significance of using indirect methods as reliable predictors of the mechanical behavior of weak rocks like tuffs. Further research is recommended to explore the application of these methods to other rock types with similar characteristics. Further research is required to compare the results with those of established direct test methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brazilian%20tensile%20strength" title="brazilian tensile strength">brazilian tensile strength</a>, <a href="https://publications.waset.org/abstracts/search?q=disc%20shear%20strength" title=" disc shear strength"> disc shear strength</a>, <a href="https://publications.waset.org/abstracts/search?q=indirect%20methods" title=" indirect methods"> indirect methods</a>, <a href="https://publications.waset.org/abstracts/search?q=tuffs" title=" tuffs"> tuffs</a>, <a href="https://publications.waset.org/abstracts/search?q=uniaxial%20compressive%20strength" title=" uniaxial compressive strength"> uniaxial compressive strength</a> </p> <a href="https://publications.waset.org/abstracts/193102/estimation-of-physico-mechanical-properties-of-tuffs-turkey-from-indirect-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193102.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">15</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3922</span> Impact Tensile Mechanical Properties of 316L Stainless Steel at Different Strain Rates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiawei%20Chen">Jiawei Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Jia%20Qu"> Jia Qu</a>, <a href="https://publications.waset.org/abstracts/search?q=Dianwei%20Ju"> Dianwei Ju</a> </p> <p class="card-text"><strong>Abstract:</strong></p> 316L stainless steel has good mechanical and technological properties, has been widely used in shipbuilding and aerospace manufacturing. In order to understand the effect of strain rate on the yield limit of 316L stainless steel and the constitutive relationship of the materials at different strain rates, this paper used the INSTRON-4505 electronic universal testing machine to study the mechanical properties of the tensile specimen under quasi-static conditions. Meanwhile, the Zwick-Roell RKP450 intelligent oscillometric impact tester was used to test the tensile specimens at different strain rates. Through the above two kinds of experimental researches, the relationship between the true stress-strain and the engineering stress-strain at different strain rates is obtained. The result shows that the tensile yield point of 316L stainless steel increases with the increase of strain rate, and the real stress-strain curve of the 316L stainless steel has a better normalization than that of the engineering stress-strain curve. The real stress-strain curves can be used in the practical engineering of impact stretch to improve its safety. <p class="card-text"><strong>Keywords:</strong> <a
