Natural frequencies and mode shape details of frame are obtained for two states, which are semi-rigid connections and elastic supports, separately. The members of this structure are analyzed as a prismatic nonlinear beam-column element in software. The mass of structure is considered as two equal lumped masses at the head of two columns in horizontal and vertical directions. Note that the degree of freedom, allocated to all nodes, is equal to three. Furthermore, the mode shapes of frame are achieved. Conclusively, the effects of connections and supports flexibility on the natural frequencies and mode shapes of structure are investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=natural%20frequency" title="natural frequency">natural frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=mode%20shape" title=" mode shape"> mode shape</a>, <a href="https://publications.waset.org/abstracts/search?q=gabled%20frame" title=" gabled frame"> gabled frame</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-rigid%20connection" title=" semi-rigid connection"> semi-rigid connection</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic%20support" title=" elastic support"> elastic support</a>, <a href="https://publications.waset.org/abstracts/search?q=OpenSees%20software" title=" OpenSees software"> OpenSees software</a> </p> <a href="https://publications.waset.org/abstracts/10248/free-vibration-analysis-of-gabled-frame-considering-elastic-supports-and-semi-rigid-connections" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10248.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">407</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">7805</span> Transverse Vibration of Elastic Beam Resting on Variable Elastic Foundation Subjected to moving Load</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Idowu%20Ibikunle%20Albert">Idowu Ibikunle Albert</a>, <a href="https://publications.waset.org/abstracts/search?q=Atilade%20Adesanya%20Oluwafemi"> Atilade Adesanya Oluwafemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Okedeyi%20Abiodun%20Sikiru"> Okedeyi Abiodun Sikiru</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustapha%20Rilwan%20Adewale"> Mustapha Rilwan Adewale</a> </p> <p class="card-text"><strong>Abstract:</strong></p> These present-day all areas of transport have experienced large advances characterized by increases in the speeds and weight of vehicles. As a result, this paper considered the Transverse Vibration of an Elastic Beam Resting on a Variable Elastic Foundation Subjected to a moving Load. The beam is presumed to be uniformly distributed and has simple support at both ends. The moving distributed moving mass is assumed to move with constant velocity. The governing equations, which are fourth-order partial differential equations, were reduced to second-order partial differential equations using an analytical method in terms of series solution and solved by a numerical method using mathematical software (Maple). Results show that an increase in the values of beam parameters, moving Mass M, and k-stiffness K, significantly reduces the deflection profile of the vibrating beam. In the results, it was equally found that moving mass is greater than moving force. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=elastic%20beam" title="elastic beam">elastic beam</a>, <a href="https://publications.waset.org/abstracts/search?q=moving%20load" title=" moving load"> moving load</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20of%20structure" title=" response of structure"> response of structure</a>, <a href="https://publications.waset.org/abstracts/search?q=variable%20elastic%20foundation" title=" variable elastic foundation"> variable elastic foundation</a> </p> <a href="https://publications.waset.org/abstracts/159577/transverse-vibration-of-elastic-beam-resting-on-variable-elastic-foundation-subjected-to-moving-load" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159577.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">121</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">7804</span> Buckling of Plates on Foundation with Different Types of Sides Support</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20N.%20Suri">Ali N.

Al-Makhlufi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper the problem of buckling of plates on foundation of finite length and with different side support is studied. The Finite Strip Method is used as tool for the analysis. This method uses finite strip elastic, foundation, and geometric matrices to build the assembly matrices for the whole structure, then after introducing boundary conditions at supports, the resulting reduced matrices is transformed into a standard Eigenvalue-Eigenvector problem. The solution of this problem will enable the determination of the buckling load, the associated buckling modes and the buckling wave length. To carry out the buckling analysis starting from the elastic, foundation, and geometric stiffness matrices for each strip a computer program FORTRAN list is developed. Since stiffness matrices are function of wave length of buckling, the computer program used an iteration procedure to find the critical buckling stress for each value of foundation modulus and for each boundary condition. The results showed the use of elastic medium to support plates subject to axial load increase a great deal the buckling load, the results found are very close with those obtained by other analytical methods and experimental work. The results also showed that foundation compensates the effect of the weakness of some types of constraint of side support and maximum benefit found for plate with one side simply supported the other free. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buckling" title="buckling">buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20strip" title=" finite strip"> finite strip</a>, <a href="https://publications.waset.org/abstracts/search?q=different%20sides%20support" title=" different sides support"> different sides support</a>, <a href="https://publications.waset.org/abstracts/search?q=plates%20on%20foundation" title=" plates on foundation"> plates on foundation</a> </p> <a href="https://publications.waset.org/abstracts/1681/buckling-of-plates-on-foundation-with-different-types-of-sides-support" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1681.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">243</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">7803</span> Stress Distribution in Axisymmetric Indentation of an Elastic Layer-Substrate Body</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kotaro%20Miura">Kotaro Miura</a>, <a href="https://publications.waset.org/abstracts/search?q=Makoto%20Sakamoto"> Makoto Sakamoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuji%20Tanabe"> Yuji Tanabe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We focus on internal stress and displacement of an elastic axisymmetric contact problem for indentation of a layer-substrate body.

A dislocation-based model, taking into account of dislocation substructures and evolutions, is applied to simulate the elastic-plastic response of both single crystal and polycrystalline aluminum. Simulated results indicate that dislocation immobilization during dynamic deformation results in a smooth increase of yield stress, which leads to the quasi-elastic release. While the generation of dislocations caused by plastic release wave results in the appearance of transition point between the quasi-elastic release and the plastic release in the profile.

The β phase in titanium alloys exhibits an elastic Young’s modulus of about 60-80 GPa, which is nearly half that of α-phase (100-120 GPa). In this work, a theoretical investigation of structural stability and thermodynamic stability, as well as the elastic properties of a quaternary Ti-Nb-Ta-Zr alloy, will be presented with an attempt to lower Young’s modulus. The structural stability and elastic properties of the alloy were evaluated using the first-principles approach within the density functional theory (DFT) framework implemented in the CASTEP code. The elastic properties include bulk modulus B, elastic Young’s modulus E, shear modulus cʹ and Poisson’s ratio v. Thermodynamic stability, as well as the fraction of β phase in the alloy, was evaluated using the Thermo-Calc software package. Thermodynamic properties such as Gibbs free energy (Δ?⁰?) and enthalpy of formation will be presented in addition to phase proportion diagrams. The stoichiometric compositions of the alloy is Ti-Nbx-Ta5-Zr5 (x = 5, 10, 20, 30, 40 at.%). An optimum alloy composition must satisfy the Born stability criteria and also possess low elastic Young’s modulus. In addition, the alloy must be thermodynamically stable, i.e., Δ?⁰? < 0. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=elastic%20modulus" title="elastic modulus">elastic modulus</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20proportion%20diagram" title=" phase proportion diagram"> phase proportion diagram</a>, <a href="https://publications.waset.org/abstracts/search?q=thermo-calc" title=" thermo-calc"> thermo-calc</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20alloys" title=" titanium alloys"> titanium alloys</a> </p> <a href="https://publications.waset.org/abstracts/141420/first-principles-calculations-and-thermo-calc-study-of-the-elastic-and-thermodynamic-properties-of-ti-nb-zr-ta-alloy-for-biomedical-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141420.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">186</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">7795</span> A Design of Active Elastic Metamaterial with Extreme Anisotropic Stiffness</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Conner%20Side">Conner Side</a>, <a href="https://publications.waset.org/abstracts/search?q=Hunter%20Pearce"> Hunter Pearce</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Traditional elastic metamaterials have difficulties in achieving independent tunable working frequency in two orthogonal directions.

When people with and without hearing disabilities press each elastic object, different sounds are produced depending on the stiffness of the elastic object. The types of sounds used were “Do Re Mi sounds.” The interface has a major advantage in that people with or without hearing disabilities can play with it.

In this paper, our interest is focused on ZnO NWs to investigate wire diameter (D<sub>wire </sub>≤ 400 nm) effects on elastic properties. The plotted data reveal that a strong size dependence of the elastic constants exists when the wire diameter is smaller than ~ 100 nm. For larger diameters (D<sub>wire</sub> > 100 nm), these ones approach their corresponding bulk values. To enrich this study, we make use of the scanning acoustic microscopy simulation technique. The calculation methodology consists of several steps: determination of longitudinal and transverse wave velocities, calculation of refection coefficients, calculation of acoustic signatures and Rayleigh velocity determination. Quantitatively, it was found that changes in ZnO diameters over the ranges 1 nm ≤ D<sub>wire</sub> ≤ 100 nm lead to similar exponential variations, for all elastic parameters, of the from: A = a + b exp(-D<sub>wire</sub>/c) where a, b, and c are characteristic constants of a given parameter. The developed relation can be used to predict elastic properties of such NW by just knowing its diameter and vice versa. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=elastic%20properties" title="elastic properties">elastic properties</a>, <a href="https://publications.waset.org/abstracts/search?q=nanowires" title=" nanowires"> nanowires</a>, <a href="https://publications.waset.org/abstracts/search?q=semiconductors" title=" semiconductors"> semiconductors</a>, <a href="https://publications.waset.org/abstracts/search?q=theoretical%20model" title=" theoretical model"> theoretical model</a>, <a href="https://publications.waset.org/abstracts/search?q=ZnO" title=" ZnO"> ZnO</a> </p> <a href="https://publications.waset.org/abstracts/77870/modeling-nanomechanical-behavior-of-zno-nanowires-as-a-function-of-nano-diameter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77870.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">7791</span> Estimation of Elastic Modulus of Soil Surrounding Buried Pipeline Using Multi-Response Surface Methodology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Won%20Mog%20Choi">Won Mog Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong%20Kyeong%20Hong"> Seong Kyeong Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Seok%20Young%20Jeong"> Seok Young Jeong </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The stress on the buried pipeline under pavement is significantly affected by vehicle loads and elastic modulus of the soil surrounding the pipeline. The correct elastic modulus of soil has to be applied to the finite element model to investigate the effect of the vehicle loads on the buried pipeline using finite element analysis. The purpose of this study is to establish the approach to calculating the correct elastic modulus of soil using the optimization process. The optimal elastic modulus of soil, which minimizes the difference between the strain measured from vehicle driving test at the velocity of 35km/h and the strain calculated from finite element analyses, was calculated through the optimization process using multi-response surface methodology. Three elastic moduli of soil (road layer, original soil, dense sand) surrounding the pipeline were defined as the variables for the optimization. Further analyses with the optimal elastic modulus at the velocities of 4.27km/h, 15.47km/h, 24.18km/h were performed and compared to the test results to verify the applicability of multi-response surface methodology. The results indicated that the strain of the buried pipeline was mostly affected by the elastic modulus of original soil, followed by the dense sand and the load layer, as well as the results of further analyses with optimal elastic modulus of soil show good agreement with the test. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pipeline" title="pipeline">pipeline</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic%20modulus%20of%20soil" title=" elastic modulus of soil"> elastic modulus of soil</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20methodology" title=" response surface methodology"> response surface methodology</a> </p> <a href="https://publications.waset.org/abstracts/44795/estimation-of-elastic-modulus-of-soil-surrounding-buried-pipeline-using-multi-response-surface-methodology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44795.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">386</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">7790</span> Effect of Elastic Modulus Anisotropy on Helical Piles Behavior in Sandy Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Ziaie%20Moayed">Reza Ziaie Moayed</a>, <a href="https://publications.waset.org/abstracts/search?q=Javad%20Shamsi%20Soosahab"> Javad Shamsi Soosahab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Helical piles are being used extensively in engineering applications all over the world. There are insufficient studies on the helical piles' behavior in anisotropic soils. In this paper, numerical modeling was adopted to investigate the effect of elastic modulus anisotropy on helical pile behavior resting on anisotropic sand by using a finite element limit analysis. The load-displacement behavior of helical piles under compression and tension loads is investigated in different relative densities of soils, and the effect of the ratio of horizontal elastic modulus with respect to vertical elastic modulus (EH/EV) is evaluated. The obtained results illustrate that in sandy soils, the anisotropic ratio of elastic modulus (EH/EV) has notable effect on bearing capacity of helical piles in different relative density.

Three modulus of elasticity in principal directions (EL, ER, ET), six Poisson’s ratios (ʋLR, ʋLT, ʋRT, ʋTR, ʋRL, ʋTL) and three shear modules (GLR, GRT, GLT) were determined. 20 x 20 x 60 mm samples were conditioned at 65 % relative humidity and 20ºC before testing. Three longitudinal and six shear wave velocities propagating along the principal axes of anisotropy, and additionally, three quasi-shear wave velocities at 45° angle with respect to the principal axes of anisotropy were measured. 2.27 MHz longitudinal and 1 MHz shear sensors were used for obtaining sound velocities. Stress-strain curves of the samples in compression tests were obtained using bi-axial extensometer in order to calculate elastic constants. Test results indicated that most of the elastic constants determined in the study are within the acceptable range. Although elastic constants determined from ultrasound are usually higher than those determined from compression tests, the values of EL and GLR determined from compression tests were higher in the study.

It is worth mentioning that the unknown coefficients are determined by implementing the principle of minimum potential energy. The numerical integration is implemented by employing the Generalized Gaussian Quadrature solution. Furthermore, with the aid of the calculated unknown coefficients, the displacement field, as well as the other parameters of the elastic field, are obtainable as well. Finally, the comparison of the previous analytical method with the current semi-analytical method proposes the efficacy of the present methodology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anisotropic%20elastic%20media" title="anisotropic elastic media">anisotropic elastic media</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-analytical%20method" title=" semi-analytical method"> semi-analytical method</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic%20field" title=" elastic field"> elastic field</a>, <a href="https://publications.waset.org/abstracts/search?q=generalized%20gaussian%20quadrature%20solution" title=" generalized gaussian quadrature solution"> generalized gaussian quadrature solution</a> </p> <a href="https://publications.waset.org/abstracts/74780/finding-the-elastic-field-in-an-arbitrary-anisotropic-media-by-implementing-accurate-generalized-gaussian-quadrature-solution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74780.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">321</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">7786</span> Determination of the Local Elastic Moduli of Shungite by Laser Ultrasonic Spectroscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elena%20B.%20Cherepetskaya">Elena B.

We used laser-ultrasonic defectoscope with wideband opto-acoustic transducer in our investigation of the velocities of longitudinal and shear elastic ultrasound waves. The duration of arising elastic pulses was less than 100 ns. Under known material thickness, the values of the velocities were determined by the time delay of the pulses reflected from the bottom surface of the sample with respect to reference pulses. The accuracy of measurement was 0.3% in the case of longitudinal wave velocity and 0.5% in the case of shear wave velocity (scanning pitch along the surface was 2 mm). On the base of found velocities of elastic waves, local elastic moduli of shungit (Young modulus, shear modulus and Poisson's ratio) were uniquely determined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laser%20ultrasonic%20testing" title="laser ultrasonic testing ">laser ultrasonic testing </a>, <a href="https://publications.waset.org/abstracts/search?q=local%20elastic%20moduli" title=" local elastic moduli"> local elastic moduli</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20wave%20velocity" title=" shear wave velocity"> shear wave velocity</a>, <a href="https://publications.waset.org/abstracts/search?q=shungit" title=" shungit"> shungit</a> </p> <a href="https://publications.waset.org/abstracts/54585/determination-of-the-local-elastic-moduli-of-shungite-by-laser-ultrasonic-spectroscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54585.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">308</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">7785</span> Effects of Elastic, Plyometric and Strength Training on Selected Anaerobic Factors in Sanandaj Elite Volleyball Players</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Majed%20Zobairy">Majed Zobairy</a>, <a href="https://publications.waset.org/abstracts/search?q=Fardin%20Kalvandi"> Fardin Kalvandi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamal%20Azizbaigi"> Kamal Azizbaigi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research was carried out for evaluation of elastic, plyometric and resistance training on selected anaerobic factors in men volleyball players.

Pre-exercise tests which include vertical jumping, 50 yard speed running and scat test were done and data were recorded. Specific exercise protocol regimen was done for each group and then post-exercise tests again were done. Data analysis showed that there were significant increases in exercise test in each group.
