The antenna is fed with coupled transverse slots on a plate laminated waveguide cavity to ensure wide bandwidth and simplicity of feeding network. The two-layer structure has one layer dedicated for feeding network and the top layer dedicated for radiating elements. It has been demonstrated that the presented feeding technique for feeding such class of array antennas can be far simple in structure and miniaturized in size when it comes to designing large phased array antenna systems.

From numerical analysis of this dispersion relation, it is shown that the stability behavior of the fast-wave mode is dependent of the dielectric constant. With a small axial momentum spreed, a super bandwidth is shown to be attainable by a mixed mode operation. Also, with the utilization from the numeric analysis of relation dispersion. We show that in the –speed mode, the constant is independent de-electric. With the ratio of dispersion of smell, high –bandwith was obtained for the combined mode.

In particular, we have investigated the competitive effect between spectral broadening arising from nonlinear refraction (optical Kerr effect) and shrinking due to two photon absorption in the InGaAsP waveguide with chi^(3) nonlinearity. The shrunk spectrum recovers broadening by the enhancement effect of the nonlinear refractive index near the bandgap of InGaAsP with a bandgap wavelength of 1490 nm. The broadened spectral width at around 1525 nm (196.7 THz) becomes 10.7 times wider than that at around 1560 nm (192.3 THz) without the enhancement effect, where amplified optical pulses with a pulse width of 2 ps and a peak power of 10 W propagate through a 1-cm-long InGaAsP waveguide with a cross-section of 4 um^2. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=InGaAsP%20waveguide" title="InGaAsP waveguide">InGaAsP waveguide</a>, <a href="https://publications.waset.org/abstracts/search?q=Chi%5E%283%29%20nonlinearity" title=" Chi^(3) nonlinearity"> Chi^(3) nonlinearity</a>, <a href="https://publications.waset.org/abstracts/search?q=spectral%20broadening" title=" spectral broadening"> spectral broadening</a>, <a href="https://publications.waset.org/abstracts/search?q=photon%20absorption" title=" photon absorption "> photon absorption </a> </p> <a href="https://publications.waset.org/abstracts/13656/spectral-broadening-in-an-ingaasp-optical-waveguide-with-kh3-nonlinearity-including-two-photon-absorption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13656.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">634</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">209</span> The Fire Performance of Exposed Timber Panels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bernice%20V.%20Y.%20Wong">Bernice V.

In term of fire resistance, cross-laminated timber panels are promoted as having excellent fire resistance, comparable to that of non-combustible materials and to heavy timber construction, due to the ability of thick wood assemblies to char slowly at a predictable rate while maintaining most of their strength during the fire exposure. This paper presents an overview of fire performance of cross-laminated timber and evaluation of its resistance to elevated temperature in comparison to homogeneous timber panels.

The result is presented for the static response of simply supported rectangular plates under uniform sinusoidal mechanical loadings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bending" title="bending">bending</a>, <a href="https://publications.waset.org/abstracts/search?q=composite" title=" composite"> composite</a>, <a href="https://publications.waset.org/abstracts/search?q=laminate" title=" laminate"> laminate</a>, <a href="https://publications.waset.org/abstracts/search?q=plates" title=" plates"> plates</a>, <a href="https://publications.waset.org/abstracts/search?q=fem" title=" fem"> fem</a> </p> <a href="https://publications.waset.org/abstracts/30849/behavior-of-laminated-plates-under-mechanical-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30849.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">406</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">205</span> Semiconductor Device of Tapered Waveguide for Broadband Optical Communications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Keita%20Iwai">Keita Iwai</a>, <a href="https://publications.waset.org/abstracts/search?q=Isao%20Tomita"> Isao Tomita</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To expand the optical spectrum for use in broadband optical communications, we study the properties of a semiconductor waveguide device with a tapered structure including its third-order optical nonlinearity.

The SaS formulation is based on choosing inside the nth layer In not equally spaced SaS parallel to the middle surface of the shell in order to introduce the electric potentials and displacements of these surfaces as basic shell variables. Such choice of unknowns permits the presentation of the proposed FG piezoelectric shell formulation in a very compact form. The SaS are located inside each layer at Chebyshev polynomial nodes that improves the convergence of the SaS method significantly. As a result, the SaS formulation can be applied efficiently to 3D solutions for FG piezoelectric laminated shells, which asymptotically approach the exact solutions of piezoelectricity as the number of SaS In goes to infinity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electroelasticity" title="electroelasticity">electroelasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=functionally%20graded%20material" title=" functionally graded material"> functionally graded material</a>, <a href="https://publications.waset.org/abstracts/search?q=laminated%20piezoelectric%20shell" title=" laminated piezoelectric shell"> laminated piezoelectric shell</a>, <a href="https://publications.waset.org/abstracts/search?q=sampling%20surfaces%20method" title=" sampling surfaces method"> sampling surfaces method</a> </p> <a href="https://publications.waset.org/abstracts/18393/numerical-modelling-of-laminated-shells-made-of-functionally-graded-elastic-and-piezoelectric-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18393.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">691</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">199</span> Time/Temperature-Dependent Finite Element Model of Laminated Glass Beams</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alena%20Zemanov%C3%A1">Alena Zemanová</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Zeman"> Jan Zeman</a>, <a href="https://publications.waset.org/abstracts/search?q=Michal%20%C5%A0ejnoha"> Michal Šejnoha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The polymer foil used for manufacturing of laminated glass members behaves in a viscoelastic manner with temperature dependence. This contribution aims at incorporating the time/temperature-dependent behavior of interlayer to our earlier elastic finite element model for laminated glass beams. The model is based on a refined beam theory: each layer behaves according to the finite-strain shear deformable formulation by Reissner and the adjacent layers are connected via the Lagrange multipliers ensuring the inter-layer compatibility of a laminated unit. The time/temperature-dependent behavior of the interlayer is accounted for by the generalized Maxwell model and by the time-temperature superposition principle due to the Williams, Landel, and Ferry. The resulting system is solved by the Newton method with consistent linearization and the viscoelastic response is determined incrementally by the exponential algorithm. By comparing the model predictions against available experimental data, we demonstrate that the proposed formulation is reliable and accurately reproduces the behavior of the laminated glass units. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title="finite element method">finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=finite-strain%20Reissner%20model" title=" finite-strain Reissner model"> finite-strain Reissner model</a>, <a href="https://publications.waset.org/abstracts/search?q=Lagrange%20multipliers" title=" Lagrange multipliers"> Lagrange multipliers</a>, <a href="https://publications.waset.org/abstracts/search?q=generalized%20Maxwell%20model" title=" generalized Maxwell model"> generalized Maxwell model</a>, <a href="https://publications.waset.org/abstracts/search?q=laminated%20glass" title=" laminated glass"> laminated glass</a>, <a href="https://publications.waset.org/abstracts/search?q=Newton%20method" title=" Newton method"> Newton method</a>, <a href="https://publications.waset.org/abstracts/search?q=Williams-Landel-Ferry%20equation" title=" Williams-Landel-Ferry equation"> Williams-Landel-Ferry equation</a> </p> <a href="https://publications.waset.org/abstracts/22985/timetemperature-dependent-finite-element-model-of-laminated-glass-beams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22985.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">431</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">198</span> Investigation of the Material Behaviour of Polymeric Interlayers in Broken Laminated Glass</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martin%20Botz">Martin Botz</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Kraus"> Michael Kraus</a>, <a href="https://publications.waset.org/abstracts/search?q=Geralt%20Siebert"> Geralt Siebert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of laminated glass gains increasing importance in structural engineering. For safety reasons, at least two glass panes are laminated together with a polymeric interlayer. In case of breakage of one or all of the glass panes, the glass fragments are still connected to the interlayer due to adhesion forces and a certain residual load-bearing capacity is left in the system. Polymer interlayers used in the laminated glass show a viscoelastic material behavior, e.g. stresses and strains in the interlayer are dependent on load duration and temperature. In the intact stage only small strains appear in the interlayer, thus the material can be described in a linear way. In the broken stage, large strains can appear and a non-linear viscoelasticity material theory is necessary. Relaxation tests on two different types of polymeric interlayers are performed at different temperatures and strain amplitudes to determine the border to the non-linear material regime. Based on the small-scale specimen results further tests on broken laminated glass panes are conducted. So-called ‘through-crack-bending’ (TCB) tests are performed, in which the laminated glass has a defined crack pattern. The test set-up is realized in a way that one glass layer is still able to transfer compressive stresses but tensile stresses have to be transferred by the interlayer solely. The TCB-tests are also conducted under different temperatures but constant force (creep test). Aims of these experiments are to elaborate if the results of small-scale tests on the interlayer are transferable to a laminated glass system in the broken stage. In this study, limits of the applicability of linear-viscoelasticity are established in the context of two commercially available polymer-interlayers. Furthermore, it is shown that the results of small-scale tests agree to a certain degree to the results of the TCB large-scale experiments. In a future step, the results can be used to develop material models for the post breakage performance of laminated glass. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glass%20breakage" title="glass breakage">glass breakage</a>, <a href="https://publications.waset.org/abstracts/search?q=laminated%20glass" title=" laminated glass"> laminated glass</a>, <a href="https://publications.waset.org/abstracts/search?q=relaxation%20test" title=" relaxation test"> relaxation test</a>, <a href="https://publications.waset.org/abstracts/search?q=viscoelasticity" title=" viscoelasticity"> viscoelasticity</a> </p> <a href="https://publications.waset.org/abstracts/91312/investigation-of-the-material-behaviour-of-polymeric-interlayers-in-broken-laminated-glass" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91312.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">122</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">197</span> Parametric Study on Dynamic Analysis of Composite Laminated Plate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Junaid%20Kameran%20Ahmed">Junaid Kameran Ahmed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A laminated plate composite of graphite/epoxy has been analyzed dynamically in the present work by using a quadratic element (8-node diso-parametric), and by depending on 1<sup>st</sup> order shear deformation theory, every node in this element has 6-degrees of freedom (displacement in x, y, and z axis and twist about x, y, and z axis). The dynamic analysis in the present work covered parametric studies on a composite laminated plate (square plate) to determine its effect on the natural frequency of the plate. The parametric study is represented by set of changes (plate thickness, number of layers, support conditions, layer orientation), and the plates have been simulated by using ANSYS package 12. The boundary conditions considered in this study, at all four edges of the plate, are simply supported and fixed boundary condition. The results obtained from ANSYS program show that the natural frequency for both fixed and simply supported increases with increasing the number of layers, but this increase in the natural frequency for the first five modes will be neglected after 10 layers. And it is observed that the natural frequency of a composite laminated plate will change with the change of ply orientation, the natural frequency increases and it will be at maximum with angle 45 of ply for simply supported laminated plate, and maximum natural frequency will be with cross-ply (0/90) for fixed laminated composite plate. It is also observed that the natural frequency increase is approximately doubled when the thickness is doubled. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laminated%20plate" title="laminated plate">laminated plate</a>, <a href="https://publications.waset.org/abstracts/search?q=orthotropic%20plate" title=" orthotropic plate"> orthotropic plate</a>, <a href="https://publications.waset.org/abstracts/search?q=square%20plate" title=" square plate"> square plate</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20frequency%20%28free%20vibration%29" title=" natural frequency (free vibration)"> natural frequency (free vibration)</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20%28graphite%20%2F%20epoxy%29" title=" composite (graphite / epoxy)"> composite (graphite / epoxy)</a> </p> <a href="https://publications.waset.org/abstracts/63332/parametric-study-on-dynamic-analysis-of-composite-laminated-plate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63332.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">348</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">196</span> Efficient Study of Substrate Integrated Waveguide Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Hajri">J.

When the glass is broken, the interlayer in between the glass sheets can stick them together. Because of this property, the hazards of sharp projectiles during natural and man-made disasters reduces. They can be widely applied in building, architecture, automotive, transport industries. Laminated glass can easily undergo large displacements even under their own weight. In order to explain their true behavior, they should be analyzed by using large deflection theory to represent nonlinear behavior. In this study, a nonlinear mathematical model is developed for the analysis of laminated glass cylindrical shell which is free in radial directions and restrained in axial directions. The results will be verified by using the results of the experiment, carried out on laminated glass cylindrical shells. The behavior of laminated composite cylindrical shell can be represented by five partial differential equations. Four of the five equations are used to represent axial displacements and radial displacements and the fifth one for the transverse deflection of the unit. Governing partial differential equations are derived by employing variational principles and minimum potential energy concept. Finite difference method is employed to solve the coupled differential equations. First, they are converted into a system of matrix equations and then iterative procedure is employed. Iterative procedure is necessary since equations are coupled. Problems occurred in getting convergent sequence generated by the employed procedure are overcome by employing variable underrelaxation factor. The procedure developed to solve the differential equations provides not only less storage but also less calculation time, which is a substantial advantage in computational mechanics problems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laminated%20glass" title="laminated glass">laminated glass</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20model" title=" mathematical model"> mathematical model</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20behavior" title=" nonlinear behavior"> nonlinear behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=PVB" title=" PVB"> PVB</a> </p> <a href="https://publications.waset.org/abstracts/42733/mechanical-behavior-of-laminated-glass-cylindrical-shell-with-hinged-free-boundary-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42733.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">319</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">191</span> CRLH and SRR Based Microwave Filter Design Useful for Communication Applications </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Subal%20Kar">Subal Kar</a>, <a href="https://publications.waset.org/abstracts/search?q=Amitesh%20Kumar"> Amitesh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Majumder"> A.

Both CRLH and SRR are unit cells used in metamaterial design. The primary aim of designing filters with such structures is to realize size reduction and also to realize novel filter performance. The CRLH based filter has been designed in microstrip transmission line, while the SRR based filter is designed with SRR loading in waveguide. The CRLH based filter designed at 2.45 GHz provides an insertion loss of 1.6 dB with harmonic suppression up to 10 GHz with 67 % size reduction when compared with a conventional edge-coupled band-pass filter designed around the same frequency. One dimensional (1-D) SRR matrix loaded in a waveguide shows the possibility of realizing a stop-band with sharp skirts in the pass-band while a stop-band in the pass-band of normal rectangular waveguide with tailoring of the dimensions of SRR unit cells. Such filters are expected to be very useful for communication systems at microwave frequency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BPF" title="BPF">BPF</a>, <a href="https://publications.waset.org/abstracts/search?q=CRLH" title=" CRLH"> CRLH</a>, <a href="https://publications.waset.org/abstracts/search?q=harmonic" title=" harmonic"> harmonic</a>, <a href="https://publications.waset.org/abstracts/search?q=metamaterial" title=" metamaterial"> metamaterial</a>, <a href="https://publications.waset.org/abstracts/search?q=SRR%20and%20waveguide" title=" SRR and waveguide"> SRR and waveguide</a> </p> <a href="https://publications.waset.org/abstracts/40047/crlh-and-srr-based-microwave-filter-design-useful-for-communication-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40047.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">427</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">190</span> Aseismic Stiffening of Architectural Buildings as Preventive Restoration Using Unconventional Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jefto%20Terzovic">Jefto Terzovic</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Kontic"> Ana Kontic</a>, <a href="https://publications.waset.org/abstracts/search?q=Isidora%20Ilic"> Isidora Ilic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the proposed design concept, laminated glass and laminated plexiglass, as ”unconventional materials”, are considered as a filling in a steel frame on which they overlap by the intermediate rubber layer, thereby forming a composite assembly. In this way vertical elements of stiffening are formed, capable for reception of seismic force and integrated into the structural system of the building. The applicability of such a system was verified by experiments in laboratory conditions where the experimental models based on laminated glass and laminated plexiglass had been exposed to the cyclic loads that simulate the seismic force. In this way the load capacity of composite assemblies was tested for the effects of dynamic load that was parallel to assembly plane. Thus, the stress intensity to which composite systems might be exposed was determined as well as the range of the structure stiffening referring to the expressed deformation along with the advantages of a particular type of filling compared to the other one. Using specialized software whose operation is based on the finite element method, a computer model of the structure was created and processed in the case study; the same computer model was used for analyzing the problem in the first phase of the design process. The stiffening system based on composite assemblies tested in laboratories is implemented in the computer model. The results of the modal analysis and seismic calculation from the computer model with stiffeners applied showed an efficacy of such a solution, thus rounding the design procedures for aseismic stiffening by using unconventional materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laminated%20glass" title="laminated glass">laminated glass</a>, <a href="https://publications.waset.org/abstracts/search?q=laminated%20plexiglass" title=" laminated plexiglass"> laminated plexiglass</a>, <a href="https://publications.waset.org/abstracts/search?q=aseismic%20stiffening" title=" aseismic stiffening"> aseismic stiffening</a>, <a href="https://publications.waset.org/abstracts/search?q=experiment" title=" experiment"> experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=laboratory%20testing" title=" laboratory testing"> laboratory testing</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20model" title=" computer model"> computer model</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a> </p> <a href="https://publications.waset.org/abstracts/150416/aseismic-stiffening-of-architectural-buildings-as-preventive-restoration-using-unconventional-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150416.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">78</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">189</span> Transient Analysis of Laminated Rubber Bearing Bridge during High Intensity Earthquake</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20M.%20Amin">N.

The analysis of laminated composite plates in three-dimensional (3D) elasticity is a complex problem, as it requires accounting for the orthotropic anisotropic nature of the material and the interactions between multiple layers. Conventional approaches, such as the classical plate theory, provide simplified solutions but are limited in performing exact analysis of the plate. To address such a challenge, the state space method emerges as a powerful numerical technique for modeling the behavior of laminated composites in 3D. The state-space method involves transforming the governing equations of elasticity into a state-space representation, enabling the analysis of complex structural systems in a systematic manner. Here, an effort is made to perform a 3D elasticity analysis of plates with cross-ply and angle-ply laminates using the state space approach. The state space approach is used in this study as it is a mixed formulation technique that gives the displacements and stresses simultaneously with the same level of accuracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross%20ply%20laminates" title="cross ply laminates">cross ply laminates</a>, <a href="https://publications.waset.org/abstracts/search?q=angle%20ply%20laminates" title=" angle ply laminates"> angle ply laminates</a>, <a href="https://publications.waset.org/abstracts/search?q=state%20space%20method" title=" state space method"> state space method</a>, <a href="https://publications.waset.org/abstracts/search?q=three-dimensional%20elasticity%20analysis" title=" three-dimensional elasticity analysis"> three-dimensional elasticity analysis</a> </p> <a href="https://publications.waset.org/abstracts/173929/3d-elasticity-analysis-of-laminated-composite-plate-using-state-space-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173929.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">111</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">187</span> Electromagnetic Interference Shielding Effectiveness of a Corrugated Rectangular Waveguide for a Microwave Conveyor-Belt Drier </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sang-Hyeon%20Bae">Sang-Hyeon Bae</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Yeon%20Kim"> Sung-Yeon Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Min-Gyo%20Jeong"> Min-Gyo Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji-Hong%20Kim"> Ji-Hong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang-Sang%20Lee"> Wang-Sang Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Traditional heating methods such as electric ovens or steam heating are slow and not very efficient.
