polymer when they break is usually thrown away, or is recycled which requires a long process. The purpose of this study is to splice the broken thermoplastic polymer using hot gas welding with different variations of welding wire/electrodes. Materials of thermoplastic polymer used are Polyethylene (PE), Polypropylene (PP), and Polyvinyl chloride (PVC) by using welding wire like the three materials. The method is carried out by using hot gas welding; there are two materials that cannot be connected, namely PE with PVC welding wire, and PP with PVC welding wire. The permeable liquid penetrant test is PP with PE welding wire, and PVC with PE welding wire. The best bending test result with the longest elongation is PE with PE welding wire with a bending test value of 179.03 kgf/mm². The microstructure was all described in Scanning Electron Microscopy (SEM) observations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermoplastic%20polymers" title="thermoplastic polymers">thermoplastic polymers</a>, <a href="https://publications.waset.org/abstracts/search?q=bending%20test" title=" bending test"> bending test</a>, <a href="https://publications.waset.org/abstracts/search?q=polyethylene%20%28PE%29" title=" polyethylene (PE)"> polyethylene (PE)</a>, <a href="https://publications.waset.org/abstracts/search?q=polypropylene%20%28PP%29" title=" polypropylene (PP)"> polypropylene (PP)</a>, <a href="https://publications.waset.org/abstracts/search?q=polyvinyl%20chloride%20%28PVC%29" title=" polyvinyl chloride (PVC)"> polyvinyl chloride (PVC)</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20gas%20welding" title=" hot gas welding"> hot gas welding</a>, <a href="https://publications.waset.org/abstracts/search?q=bending%20test" title=" bending test"> bending test</a> </p> <a href="https://publications.waset.org/abstracts/136833/bending-test-characteristics-for-splicing-of-thermoplastic-polymer-using-hot-gas-welding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136833.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">202</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">9628</span> Out-of-Plane Bending Properties of Out-of-Autoclave Thermosetting Prepregs during Forming Processes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hassan%20A.%20Alshahrani">Hassan A.

The finite element analysis (FEA) found 1.68 N (normal group) and 1.39 N (osteoporosis group) in the average maximum force, and 4.32 N/mm (normal group) and 3.56 N/mm (osteoporosis group) in the average stiffness. In the comparison of the 3-point bending test results, the maximum force and the stiffness were different about 9.4 times in the normal group and about 11.2 times in the osteoporosis group. The difference between the analysis and the test was greatly significant and this result demonstrated improvement points of the material properties applied to the computational analysis of this study. For the next study, the material properties of the mouse femur will be supplemented through additional computational analysis and test. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3-point%20bending%20test" title="3-point bending test">3-point bending test</a>, <a href="https://publications.waset.org/abstracts/search?q=mouse" title=" mouse"> mouse</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoporosis" title=" osteoporosis"> osteoporosis</a>, <a href="https://publications.waset.org/abstracts/search?q=FEA" title=" FEA"> FEA</a> </p> <a href="https://publications.waset.org/abstracts/54813/study-on-3d-fe-analysis-on-normal-and-osteoporosis-mouse-models-based-on-3-point-bending-tests" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54813.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">351</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">9625</span> Multifunctional Bending and Straightening Machines for Shipbuilding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20Yu.%20Shungin">V.

In particular, conventional bending technologies with dies are being replaced with resource-saving methods of rotation (roller) banding. Such rolling bending is performed by multiple rolling of a plat in special bending rollers. Studies, conducted in JSC SSTC, allowed developing a theory of rotation bending, methods for calculation of process parameters, requirements to roller presses and bending accessories. This technology allows replacing old and expensive presses with new cheaper roller ones, having less power consumption and bending force. At first, roller presses were implemented in ship repair, however now they are widely employed at major shipbuilding yards. JSC SSTC develops bending technology and carries out design, manufacturing and delivery of roller presses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bending%2Fstraightening%20machines" title="bending/straightening machines">bending/straightening machines</a>, <a href="https://publications.waset.org/abstracts/search?q=rotational%20bending" title=" rotational bending"> rotational bending</a>, <a href="https://publications.waset.org/abstracts/search?q=ship%20hull%20structures" title=" ship hull structures"> ship hull structures</a>, <a href="https://publications.waset.org/abstracts/search?q=multifunctional%20bending" title=" multifunctional bending"> multifunctional bending</a> </p> <a href="https://publications.waset.org/abstracts/6847/multifunctional-bending-and-straightening-machines-for-shipbuilding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6847.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">576</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">9624</span> A Comparative Study of Force Prediction Models during Static Bending Stage for 3-Roller Cone Frustum Bending</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahesh%20Chudasama">Mahesh Chudasama</a>, <a href="https://publications.waset.org/abstracts/search?q=Harit%20Raval"> Harit Raval</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Conical sections and shells of metal plates manufactured by 3-roller conical bending process are widely used in the industries. The process is completed by first bending the metal plates statically and then dynamic roller bending sequentially. It is required to have an analytical model to get maximum bending force, for optimum design of the machine, for static bending stage. Analytical models assuming various stress conditions are considered and these analytical models are compared considering various parameters and reported in this paper. It is concluded from the study that for higher bottom roller inclination, the shear stress affects greatly to the static bending force whereas for lower bottom roller inclination it can be neglected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=roller-bending" title="roller-bending">roller-bending</a>, <a href="https://publications.waset.org/abstracts/search?q=static-bending" title=" static-bending"> static-bending</a>, <a href="https://publications.waset.org/abstracts/search?q=stress-conditions" title=" stress-conditions"> stress-conditions</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical-modeling" title=" analytical-modeling"> analytical-modeling</a> </p> <a href="https://publications.waset.org/abstracts/45482/a-comparative-study-of-force-prediction-models-during-static-bending-stage-for-3-roller-cone-frustum-bending" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45482.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">251</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">9623</span> A Study on the Comparatison of Mechanical and Thermal Properties According to Laminated Orientation of CFRP through Bending Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hee%20Jae%20Shin">Hee Jae Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Lee%20Ku%20Kwac"> Lee Ku Kwac</a>, <a href="https://publications.waset.org/abstracts/search?q=In%20Pyo%20Cha"> In Pyo Cha</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Sang%20Lee"> Min Sang Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Kyung%20Yoon"> Hyun Kyung Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Gun%20Kim"> Hong Gun Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In rapid industrial development has increased the demand for high-strength and lightweight materials. Thus, various CFRP (Carbon Fiber Reinforced Plastics) with composite materials are being used. The design variables of CFRP are its lamination direction, order, and thickness. Thus, the hardness and strength of CFRP depend much on their design variables. In this paper, the lamination direction of CFRP was used to produce a symmetrical ply [0°/0°, -15°/+15°, -30°/+30°, -45°/+45°, -60°/+60°, -75°/+75°, and 90°/90°] and an asymmetrical ply [0°/15°, 0°/30°, 0°/45°, 0°/60° 0°/75°, and 0°/90°]. The bending flexure stress of the CFRP specimen was evaluated through a bending test. Its thermal property was measured using an infrared camera. The symmetrical specimen and the asymmetrical specimen were analyzed. The results showed that the asymmetrical specimen increased the bending loads according to the increase in the orientation angle; and from 0°, the symmetrical specimen showed a tendency opposite the asymmetrical tendency because the tensile force of fiber differs at the vertical direction of its load. Also, the infrared camera showed that the thermal property had a trend similar to that of the mechanical properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carbon%20Fiber%20Reinforced%20Plastic%20%28CFRP%29" title="Carbon Fiber Reinforced Plastic (CFRP)">Carbon Fiber Reinforced Plastic (CFRP)</a>, <a href="https://publications.waset.org/abstracts/search?q=bending%20test" title=" bending test"> bending test</a>, <a href="https://publications.waset.org/abstracts/search?q=infrared%20camera" title=" infrared camera"> infrared camera</a>, <a href="https://publications.waset.org/abstracts/search?q=composite" title=" composite"> composite</a> </p> <a href="https://publications.waset.org/abstracts/21385/a-study-on-the-comparatison-of-mechanical-and-thermal-properties-according-to-laminated-orientation-of-cfrp-through-bending-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21385.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">398</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">9622</span> Investigation on Flexural Behavior of Non-Crimp 3D Orthogonal Weave Carbon Composite Reinforcement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sh.%20Minapoor">Sh.

For this purpose, the three-point bending test method is used and the load-displacement curves are analyzed. The influence of some weave's parameters such as yarn type, geometry of structure, and fiber volume fraction on bending behavior of non-crimp 3D orthogonal carbon fabric is investigated.

After conditioning, test specimens were loaded in the laboratory conditions onto an universal testing machine and the failure load was measured. Data was recalculated by using goniometric, bending moment and stiffness equation to the stiffness coefficients and the bending moments were investigated. The results showed difference that was observed for the mortise with tenon joint and the dowel joint. This difference was explained by a varied adhesive bond area, which is related to the dimensions of dowels (diameter and length) as well. The bending moments and stiffness ware (except of type of corner joint) also affected by type of used adhesive, type of dowels and wood species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corner%20joint" title="corner joint">corner joint</a>, <a href="https://publications.waset.org/abstracts/search?q=wooden%20window" title=" wooden window"> wooden window</a>, <a href="https://publications.waset.org/abstracts/search?q=bending%20moment" title=" bending moment"> bending moment</a>, <a href="https://publications.waset.org/abstracts/search?q=stiffness" title=" stiffness"> stiffness</a> </p> <a href="https://publications.waset.org/abstracts/82921/review-for-mechanical-tests-of-corner-joints-on-wooden-windows-and-effects-to-the-stiffness" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82921.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">218</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">9620</span> Comparative Study of Concrete Filled Steel I-Girder Bridge with Conventional Type of Bridge </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Waheed%20Ahmad%20Safi">Waheed Ahmad Safi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shunichi%20Nakamura"> Shunichi Nakamura</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Habib%20Ghaforzai"> Abdul Habib Ghaforzai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Steel and concrete composite bridge with concrete filled steel I-girder (CFIG) was proposed and FEM and laboratory tests were conducted to analysis bending and shear behavior.

Hassan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rotary draw bending is a method which is being used in tube forming. In the tube bending process, the neutral axis moves towards the inner arc and the wall thickness distribution changes for tube’s cross section. Thinning takes place in the outer arc of the tube (extrados) due to the stretching of the material, whereas thickening occurs in the inner arc of the tube (intrados) due to the comparison of the material. The calculations of the wall thickness distribution, neutral axis shifting, and strain distribution have not been accurate enough, so far. The previous model (the geometrical model) describes the neutral axis shifting and wall thickness distribution. The geometrical of the tube, bending radius and bending angle are considered in the geometrical model, while the influence of the material properties of the tube forming are ignored. The advanced model is a modification of the previous model using material properties that depends on the correction factor. The correction factor is a purely empirically determined factor. The advanced model was compared with the Finite element simulation (FE simulation) using a different bending factor (Bf=bending radius/ diameter of the tube), wall thickness (Wf=diameter of the tube/ wall thickness), and material properties (strain hardening exponent). Finite element model of rotary draw bending has been performed in PAM-TUBE program (version: 2012). Results from the advanced model resemble the FE simulation and the experimental test. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rotary%20draw%20bending" title="rotary draw bending">rotary draw bending</a>, <a href="https://publications.waset.org/abstracts/search?q=material%20properties" title=" material properties"> material properties</a>, <a href="https://publications.waset.org/abstracts/search?q=neutral%20axis%20shifting" title=" neutral axis shifting"> neutral axis shifting</a>, <a href="https://publications.waset.org/abstracts/search?q=wall%20thickness%20distribution" title=" wall thickness distribution"> wall thickness distribution</a> </p> <a href="https://publications.waset.org/abstracts/18270/advanced-model-for-calculation-of-the-neutral-axis-shifting-and-the-wall-thickness-distribution-in-rotary-draw-bending-processes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18270.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">397</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">9616</span> Theoretical and Experimental Bending Properties of Composite Pipes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maja%20Stefanovska">Maja Stefanovska</a>, <a href="https://publications.waset.org/abstracts/search?q=Svetlana%20Risteska"> Svetlana Risteska</a>, <a href="https://publications.waset.org/abstracts/search?q=Blagoja%20Samakoski"> Blagoja Samakoski</a>, <a href="https://publications.waset.org/abstracts/search?q=Gari%20Maneski"> Gari Maneski</a>, <a href="https://publications.waset.org/abstracts/search?q=Biljana%20Kostadinoska"> Biljana Kostadinoska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim of this work is to determine the theoretical and experimental properties of filament wound glass fiber/epoxy resin composite pipes with different winding design subjected under bending.

Machinery manufacturing industry is one of the major resource consumers on a global scale. Even though the incessant finding out of the new material, metals, and resources, it is urgent for the industry to develop methods to use the Earth's resources intelligently and more sustainable than before. Re-engineering of machine tools regarding design and failure analysis is an approach whereby out-of-date machines are upgraded and returned to useful life. To ensure the reliable future performance of the used machine components, it is essential to investigate the machine component failure through the material, design, and surface examinations. This paper presents an experimental approach aimed at inspecting the shaft of the rotary draw bending machine as a case to study. The testing methodology, which is based on the principle of the three-point bending test, allows assessing the shaft elastic behavior under loading. Furthermore, the shaft elastic characteristics include the maximum linear deflection, and maximum bending stress was determined by using an analytical approach and finite element (FE) analysis approach. In the end, the results were compared with the ones obtained by the experimental approach. In conclusion, it is seen that the measured bending deflection and bending stress were well close to the permissible design value. Therefore, the shaft can work in the second life cycle. However, based on previous surface tests conducted, the shaft needs surface treatments include re-carburizing and refining processes to ensure the reliable surface performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deflection" title="deflection">deflection</a>, <a href="https://publications.waset.org/abstracts/search?q=FE%20analysis" title=" FE analysis"> FE analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=shaft" title=" shaft"> shaft</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=three-point%20bending" title=" three-point bending"> three-point bending</a> </p> <a href="https://publications.waset.org/abstracts/92854/experimental-and-numerical-evaluation-of-a-shaft-failure-behaviour-using-three-point-bending-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92854.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">158</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">9614</span> Experimental Study on Bending and Torsional Strength of Bulk Molding Compound Seat Back Frame Part</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hee%20Yong%20Kang">Hee Yong Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyeon%20Ho%20Shin"> Hyeon Ho Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jung%20Cheol%20Yoo"> Jung Cheol Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Il%20Taek%20Lee"> Il Taek Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung%20Mo%20Yang"> Sung Mo Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lightweight technology using composites is being developed for vehicle seat structures, and its design must meet the safety requirements. According to the Federal Motor Vehicle Safety Standard (FMVSS) 207 seating systems test procedure, the back moment load is applied to the seat back frame structure for the safety evaluation of the vehicle seat. The seat back frame using the composites is divided into three parts: upper part frame, and left- and right-side frame parts following the manufacturing process. When a rear moment load is applied to the seat back frame, the side frame receives the bending load and the torsional load at the same time. This results in the largest loaded strength. Therefore, strength test of the component unit is required. In this study, a component test method based on the FMVSS 207 seating systems test procedure was proposed for the strength analysis of bending load and torsional load of the automotive Bulk Molding Compound (BMC) Seat Back Side Frame. Moreover, strength evaluation according to the carbon band reinforcement was performed. The back-side frame parts of the seat that are applied to the test were manufactured through BMC that is composed of vinyl ester Matrix and short carbon fiber. Then, two kinds of reinforced and non-reinforced parts of carbon band were formed through a high-temperature compression molding process. In addition, the structure that is applied to the component test was constructed by referring to the FMVSS 207. Then, the bending load and the torsional load were applied through the displacement control to perform the strength test for four load conditions. The results of each test are shown through the load-displacement curves of the specimen. The failure strength of the parts caused by the reinforcement of the carbon band was analyzed. Additionally, the fracture characteristics of the parts for four strength tests were evaluated, and the weakness structure of the back-side frame of the seat structure was confirmed according to the test conditions. Through the bending and torsional strength test methods, we confirmed the strength and fracture characteristics of BMC Seat Back Side Frame according to the carbon band reinforcement. And we proposed a method of testing the part strength of a seat back frame for vehicles that can meet the FMVSS 207. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seat%20back%20frame" title="seat back frame">seat back frame</a>, <a href="https://publications.waset.org/abstracts/search?q=bending%20and%20torsional%20strength" title=" bending and torsional strength"> bending and torsional strength</a>, <a href="https://publications.waset.org/abstracts/search?q=BMC%20%28Bulk%20Molding%20Compound%29" title=" BMC (Bulk Molding Compound)"> BMC (Bulk Molding Compound)</a>, <a href="https://publications.waset.org/abstracts/search?q=FMVSS%20207%20seating%20systems" title=" FMVSS 207 seating systems"> FMVSS 207 seating systems</a> </p> <a href="https://publications.waset.org/abstracts/92200/experimental-study-on-bending-and-torsional-strength-of-bulk-molding-compound-seat-back-frame-part" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92200.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">210</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">9613</span> Bending Effect on POF Splitter Performance for Different Thickness of Fiber Cores</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20S.%20Supian">L.

The DoB exhibits considerable scatter calling for greater emphasis in accurate determination of its governing probability distribution which is a key input for the fatigue reliability analysis of a tubular joint. Although the tubular X-joints are commonly found in offshore jacket structures, as far as the authors are aware, no comprehensive research has been carried out on the probability distribution of the DoB in tubular X-joints. What has been used so far as the probability distribution of the DoB in reliability analyses is mainly based on assumptions and limited observations, especially in terms of distribution parameters. In the present paper, results of parametric equations available for the calculation of the DoB have been used to develop probability distribution models for the DoB in the chord member of tubular X-joints subjected to four types of bending loads. Based on a parametric study, a set of samples was prepared and density histograms were generated for these samples using Freedman-Diaconis method. Twelve different probability density functions (PDFs) were fitted to these histograms. The maximum likelihood method was utilized to determine the parameters of fitted distributions. In each case, Kolmogorov-Smirnov test was used to evaluate the goodness of fit. Finally, after substituting the values of estimated parameters for each distribution, a set of fully defined PDFs have been proposed for the DoB in tubular X-joints subjected to bending loads. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tubular%20X-joint" title="tubular X-joint">tubular X-joint</a>, <a href="https://publications.waset.org/abstracts/search?q=degree%20of%20bending%20%28DoB%29" title=" degree of bending (DoB)"> degree of bending (DoB)</a>, <a href="https://publications.waset.org/abstracts/search?q=probability%20density%20function%20%28PDF%29" title=" probability density function (PDF)"> probability density function (PDF)</a>, <a href="https://publications.waset.org/abstracts/search?q=Kolmogorov-Smirnov%20goodness-of-fit%20test" title=" Kolmogorov-Smirnov goodness-of-fit test"> Kolmogorov-Smirnov goodness-of-fit test</a> </p> <a href="https://publications.waset.org/abstracts/20736/development-of-probability-distribution-models-for-degree-of-bending-dob-in-chord-member-of-tubular-x-joints-under-bending-loads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20736.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">719</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">9610</span> Bending and Shear Characteristics of Hollowcore Slab with Polystyrene Forms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kang%20Kun%20Lee">Kang Kun Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> New I-slab system with polystyrene forms and precast concrete deck is proposed to reduce the construction period and the self-weight of the slab.

The main parameters of experiments are diameters of the holes made by polystyrene form and the thickness of slab. Structural performance of I-slab is evaluated on the basis of failure mode, load-displacement curve, and ultimate strengths. Based on the test results, it is found that the critical punching shear sections are changed as the test variables are different, hence resulting in the varied punching shear strengths.

The theoretical estimate of the magnitude maximum bending moment for the piles was considering a vertical rigid pile under an inclined load and using semi-empirical relations. The length of the equivalent rigid pile was based on the relative stiffness factor of the pile. Model tests were carried out using instrumented piles of wide-ranging flexibilities. The piles were buried in loose sand at batter angles of β=±150, β=±300 and were applied to incrementally increasing lateral loads. The pile capacities and the variation of bending moment along the pile shaft were measured. The new coefficient of 0.5 was proposed to estimate the bending moment of a flexible batter pile in the sand under horizontal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=batter%20pile" title="batter pile">batter pile</a>, <a href="https://publications.waset.org/abstracts/search?q=bending%20moment" title=" bending moment"> bending moment</a>, <a href="https://publications.waset.org/abstracts/search?q=sand" title=" sand"> sand</a>, <a href="https://publications.waset.org/abstracts/search?q=horizontal%20loads" title=" horizontal loads"> horizontal loads</a> </p> <a href="https://publications.waset.org/abstracts/190372/bending-moment-of-flexible-batter-pile-in-sands-under-horizontal-loads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190372.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">22</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">9608</span> Effect of Short Chain Alcohols on Bending Rigidity of Lipid Bilayer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Buti%20Suryabrahmam">Buti Suryabrahmam</a>, <a href="https://publications.waset.org/abstracts/search?q=V.%20A.%20Raghunathan"> V.

The Bending rigidity of 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) membrane was measured at 28 °C by employing Vesicle Fluctuation Analysis technique. The concentration and chain length (n) of alcohol in the buffer solution were varied from 0 to 1.5 M and from 2 to 8 respectively. We observed a non-linear reduction in the bending rigidity from ~17×10⁻²⁰ J to ~10×10⁻²⁰ J, for all chain lengths of alcohols used in our experiment. We observed approximately three orders of the concentration difference between ethanol and octanol, to show the similar reduction in the bending values. We attribute this phenomenon to thinning of the bilayer due to the adsorption of alcohols at the bilayer-water interface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alcohols" title="alcohols">alcohols</a>, <a href="https://publications.waset.org/abstracts/search?q=bending%20rigidity" title=" bending rigidity"> bending rigidity</a>, <a href="https://publications.waset.org/abstracts/search?q=DMPC" title=" DMPC"> DMPC</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid%20bilayers" title=" lipid bilayers"> lipid bilayers</a> </p> <a href="https://publications.waset.org/abstracts/100295/effect-of-short-chain-alcohols-on-bending-rigidity-of-lipid-bilayer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100295.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">9607</span> Development and Characterization of Sandwich Bio-Composites Based on Short Alfa Fiber and Jute Fabric</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amine%20Rezzoug">Amine Rezzoug</a>, <a href="https://publications.waset.org/abstracts/search?q=Selsabil%20Rokia%20Laraba"> Selsabil Rokia Laraba</a>, <a href="https://publications.waset.org/abstracts/search?q=Mourad%20Ancer"> Mourad Ancer</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Abdi"> Said Abdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Composite materials are taking center stage in different fields thanks to their mechanical characteristics and their ease of preparation. Environmental constraints have led to the development of composite with natural reinforcements. The sandwich structure has the advantage to have good flexural proprieties for low density, which is why it was chosen in this work. The development of these materials is related to an energy saving strategy and environmental protection. The present work refers to the study of the development and characterization of sandwiches composites based on hybrids laminates with natural reinforcements (Alfa and Jute), a metal fabric was introduced into composite in order to have a compromise between weight and properties. We use different configurations of reinforcements (jute, metallic fabric) to develop laminates in order to use them as thin facings for sandwiches materials. While the core was an epoxy matrix reinforced with Alfa short fibers, a chemical treatment sodium hydroxide was cared to improve the adhesion of the Alfa fibers. The mechanical characterization of our materials was made by the tensile and bending test, to highlight the influence of jute and Alfa. After testing, the fracture surfaces are observed by scanning electron microscopy (SEM). Optical microscopy allowed us to calculate the degree of porosity and to observe the morphology of the individual layers. Laminates based on jute fabric have shown better results in tensile test as well as to bending, compared to those of the metallic fabric (100%, 65%). Sandwich Panels were also characterized in terms of bending test. Results we had provide, shows that this composite has sufficient properties for possible replacing conventional composite materials by considering the environmental factors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bending%20test" title="bending test">bending test</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-composites" title=" bio-composites"> bio-composites</a>, <a href="https://publications.waset.org/abstracts/search?q=sandwiches" title=" sandwiches"> sandwiches</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/35497/development-and-characterization-of-sandwich-bio-composites-based-on-short-alfa-fiber-and-jute-fabric" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35497.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">435</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">9606</span> Polarization Dependent Flexible GaN Film Nanogenerators and Electroluminescence Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeong%20Min%20Baik">Jeong Min Baik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present that the electroluminescence (EL) properties and electrical output power of flexible N-face p-type GaN thin films can be tuned by strain-induced piezo-potential generated across the metal-semiconductor-metal structures. Under different staining conditions (convex and concave bending modes), the transport properties of the GaN films can be changed due to the spontaneous polarization of the films. The I-V characteristics with the bending modes show that the convex bending can increase the current across the films by the decrease in the barrier height at the metal-semiconductor contact, increasing the EL intensity of the P-N junction. At convex bending, it is also shown that the flexible p-type GaN films can generate an output voltage of up to 1.0 V, while at concave bending, 0.4 V. The change of the band bending with the crystal polarity of GaN films was investigated using high-resolution photoemission spectroscopy.

In this research, the asphalt mixture was modified with carbon nanotubes ranging from 0.2% to 2% of binder to study the effect of CNT modification on rutting potential and fatigue life of asphalt mixtures. During this study, the conventional and modified asphalt mixture was subjected to a uni-axial dynamic creep test and dry Hamburg wheel tracking test to study rutting resistance. Fatigue behavior of asphalt mixture was studied using a four-point bending test apparatus. The plateau value of asphalt mixture was taken as a measure of fatigue performance according to the ratio of dissipated energy approach.

In the case of flange local bending, the capacity equations were primarily formulated for an interior point along the member, which is defined to be at a distance larger than ten flange thicknesses away from the member’s end. When a concentrated load is applied within ten flange thicknesses from the member’s end, AISC requires a fifty percent reduction to be applied to the flange bending capacity. This reduction, however, is not supported by any research. In this study, finite element modeling is used to investigate the actual reduction in capacity near the end of such a steel member. The results indicate that the AISC equation for flange local bending is quite conservative for forces applied at less than ten flange thicknesses from the member’s end and a new equation is suggested for the evaluation of available flange local bending capacity within that distance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flange%20local%20bending" title="flange local bending">flange local bending</a>, <a href="https://publications.waset.org/abstracts/search?q=concentrated%20forces" title=" concentrated forces"> concentrated forces</a>, <a href="https://publications.waset.org/abstracts/search?q=column" title=" column"> column</a>, <a href="https://publications.waset.org/abstracts/search?q=flange%20capacity" title=" flange capacity"> flange capacity</a> </p> <a href="https://publications.waset.org/abstracts/22697/evaluation-of-flange-bending-capacity-near-member-end-using-a-finite-element-analysis-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22697.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">686</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">9601</span> Checking Planetary Clutch on the Romania Tractor Using Mathematical Equations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Vahedi%20Torshizi">Mohammad Vahedi Torshizi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this investigation, at first, bending stress, contact stress, Safety factor of bending and Safety factor of contact between sun gear and planet gear tooth was determined using mathematical equations.

In this paper, Artificial Neural Network and Fuzzy Logic System were used to predict of bending angle in laser forming process. Inputs to these models were laser travel speed and laser power. The comparison between artificial neural network and fuzzy logic models with experimental results has been shown both of these models have high ability to prediction of bending angles with minimum errors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20network" title="artificial neural network">artificial neural
