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">584</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">583</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.

A direct method for characterizing the bending behavior of composite prepregs was developed.

Good correlation between theoretical and experimental results has been obtained, where sample No4 has shown the highest value of bending strength. All samples have demonstrated matrix cracking and fiber failure followed by layers delamination during testing. Also, it was found that smaller winding angles lead to an increase in bending stress.

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 尾=卤150, 尾=卤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">578</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 掳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脳10鈦宦测伆 J to ~10脳10鈦宦测伆 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">577</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. This study has great significance on the practical applications of GaN in optoelectronic devices and nanogenerators under a working environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GaN" title="GaN">GaN</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible" title=" flexible"> flexible</a>, <a href="https://publications.waset.org/abstracts/search?q=laser%20lift-off" title=" laser lift-off"> laser lift-off</a>, <a href="https://publications.waset.org/abstracts/search?q=nanogenerator" title=" nanogenerator"> nanogenerator</a> </p> <a href="https://publications.waset.org/abstracts/13583/polarization-dependent-flexible-gan-film-nanogenerators-and-electroluminescence-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13583.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">419</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">576</span> In-situ Observations Using SEM-EBSD for Bending Deformation in Single-Crystal Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuko%20Matayoshi">Yuko Matayoshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Takashi%20Sakai"> Takashi Sakai</a>, <a href="https://publications.waset.org/abstracts/search?q=Yin-Gjum%20Jin"> Yin-Gjum Jin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun-ichi%20Koyama"> Jun-ichi Koyama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To elucidate the material characteristics of single crystals of pure aluminum and copper, the respective relations between crystallographic orientations and micro structures were examined, along with bending and mechanical properties.

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鈥檚 end. When a concentrated load is applied within ten flange thicknesses from the member鈥檚 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鈥檚 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">572</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.

This paper investigates the tube bending with rotary draw bending process using thick-walled tubes and different material properties (16Mo3 and 10CrMo9-10). The experimental tests and finite element simulations are used to calculate the variable characteristics (wall thickness distribution, neutral axis shifting and longitudinal strain distribution).

HEAs have very good mechanical properties (in particular, alloys based on CoCrNi). They also show the ability to maintain their strength at high temperatures, which is extremely important in some applications. AlCoCrFeNi alloy is one of the most studied high-entropy alloys. Scientists often study the effect of changing the aluminum content in this alloy because it causes significant changes in phase presence and microstructure and consequently affects its hardness, ductility, and other properties. Research conducted by the authors also investigates the effect of aluminium content in Al鈧揅oCrFeNi alloy on its microstructure and mechanical properties. Al鈧揅oCrFeNi alloys were prepared by vacuum induction melting. The obtained samples were examined for chemical composition, microstructure, and microhardness. The three-point bending method was carried out to determine the bending strength, bending modulus, and conventional bending yield strength. The obtained results confirm the influence of aluminum content on the properties of Al鈧揅oCrFeNi alloy. Most studies on Al鈧揅oCrFeNi alloy focus on the determination of mechanical properties in compression or tension, much less in bending. The achieved results provide valuable information on the bending properties of Al鈧揅oCrFeNi alloy and lead to interesting conclusions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bending%20properties" title="bending properties">bending properties</a>, <a href="https://publications.waset.org/abstracts/search?q=high-entropy%20alloys" title=" high-entropy alloys"> high-entropy alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=induction%20melting" title=" induction melting"> induction melting</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a> </p> <a href="https://publications.waset.org/abstracts/137068/effect-of-aluminium-content-on-bending-properties-and-microstructure-of-alcocrfeni-alloy-fabricated-by-induction-melting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137068.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">149</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">568</span> Advanced Model for Calculation of the Neutral Axis Shifting and the Wall Thickness Distribution in Rotary Draw Bending Processes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20Engel">B.

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鈥檚 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">567</span> Docking Studie of Biologically Active Molecules: Exploring Medical Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sihame%20Amakrane">Sihame Amakrane</a>, <a href="https://publications.waset.org/abstracts/search?q=Zineb%20Ouahdi"> Zineb Ouahdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Salah"> Mohammed Salah</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Belaaouad"> Said Belaaouad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> \This research explores the efficacy of novel pyrimidine derivatives on bacterial strains such as Escherichia coli, Staphylococcus aureus, and Myccobacterium tuberculosis, utilizing bending energy calculations.

The bending and shear tests of the CFIG were carried out, showing that the bending strength of CFIG was 2.8 times of the conventional steel I-girder and the shear strength was 3.0 times of the steel I-girder. Finite element models were established to clarify bending and shear behaviors and the load transfer mechanism of CFIG. FEM result agreed very well with the test results. The FEM model was also applied to simulate the shear tests of the CFIG specimens.

The papers theme is soil-structure interaction in the ground of soil retaining structures. The secant pile wall is the concern, while the focus is its capping beam. The earlier papers suggested a technique to structurally analyze capping beam. It has been proved that; pile rigidity shares the capping beam rigidity to resist the wall deformations. The current paper explains how the beam-pile integration re-distributes the pile鈥檚 bending moment for the benefits of wall deformations. It is concluded that re-distribution of pile bending moment is completely different than the calculated by plain strain analysis, values, and distributions. The pile diameter, beam rigidity, pile spacing, and the 3D-analysis-effect individually or all together affect the pile bending moment. The Plaxis-2D and STAAD-Pro 3D are the used software鈥檚. Throughout this study, three sand densities, various pile and beam rigidities, and three excavation depths, i.e., 3.0-m, 4.0-m and 5.0-m have been considered. <p class="card-text"><strong>Keywords:</strong> <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=capping%20beam" title=" capping beam"> capping beam</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20analysis" title=" numerical analysis"> numerical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=secant%20pile" title=" secant pile"> secant pile</a>, <a href="https://publications.waset.org/abstracts/search?q=sandy%20soil" title=" sandy soil"> sandy soil</a> </p> <a href="https://publications.waset.org/abstracts/134926/cantilever-secant-pile-constructed-in-sand-capping-beam-piles-bending-moments-interaction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134926.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">182</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">562</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.

The formulated elements are based on the strain based approach. This approach leads to the representation of the displacements by higher order polynomial terms without the need for the introduction of additional internal and unnecessary degrees of freedom. Good convergence can also be obtained when the results are compared with those obtained from the corresponding displacement based elements, having the same total number of degrees of freedom. Furthermore, the plate bending elements are free from any shear locking since they converge to the Kirchhoff solution for thin plates contrarily for the corresponding displacement based elements. In this paper the efficiency of the strain based approach compared to well known displacement formulation is presented. The results obtained by a new formulated plate bending element based on the strain approach and Kirchhoff theory are compared with some others elements. The good convergence of the new formulated element is confirmed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=displacement%20fields" title="displacement fields">displacement fields</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20elements" title=" finite elements"> finite elements</a>, <a href="https://publications.waset.org/abstracts/search?q=plate%20bending" title=" plate bending"> plate bending</a>, <a href="https://publications.waset.org/abstracts/search?q=Kirchhoff%20theory" title=" Kirchhoff theory"> Kirchhoff theory</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20based%20approach" title=" strain based approach"> strain based approach</a> </p> <a href="https://publications.waset.org/abstracts/10902/efficiency-of-the-strain-based-approach-formulation-for-plate-bending-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10902.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">296</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">559</span> A 3D Eight Nodes Brick Finite Element Based on the Strain Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Belounar">L.

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掳/0掳, -15掳/+15掳, -30掳/+30掳, -45掳/+45掳, -60掳/+60掳, -75掳/+75掳, and 90掳/90掳] and an asymmetrical ply [0掳/15掳, 0掳/30掳, 0掳/45掳, 0掳/60掳 0掳/75掳, and 0掳/90掳]. 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掳, 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">557</span> Deformation of Metallic Foams with Closed Cell at High Temperatures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emrah%20Ersoy">Emrah Ersoy</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Ozcatalbas"> Yusuf Ozcatalbas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to investigate formability of Al based closed cell metallic foams at high temperature. The foam specimens with rectangular section were produced from AlMg1Si0.6TiH20.8 alloy preform material. Bending and free bending tests based on gravity effect were applied to foam specimens at high temperatures. During the tests, the time-angular deformation relationships with various temperatures were determined. Deformation types formed in cell walls were investigated by means of Scanning Electron Microscopy (SEM) and optical microscopy. Bending deformation about 90掳 was achieved without any defect at high temperatures. The importance of a critical temperature and deformation rate was emphasized in maintaining the deformation. Significant slip lines on surface of cell walls at tensile zones of bending specimen were observed. At high strain rates, the microcrack formation in boundaries of elongated grains was determined. <p class="card-text"><strong>Keywords:</strong> <a
