An exact solution is obtained for three-dimensional deformations of a simply supported functionally graded rectangular plate subjected to mechanical and thermal loads on its top and/or bottom surfaces. Suitable temperature and displacement functions that identically satisfy boundary conditions at the edges are used to reduce the partial differential equations governing the thermomechanical defo...

the effect of a distributed patch mass on the natural frequency of vibration of a laminated rectangular plate with simply supported boundaries is investigated. the third order displacement field of a composite laminated rectangular plate is defined using the two variable refined plate theory. equations of motion of the plate are obtained with the help of calculus of variation. parametric study ...

Exact solutions are derived for three-dimensional, anisotropic, linearly magneto-electroelastic, simply-supported, and multilayered rectangular plates under static loadings. While the homogeneous solutions are obtained in terms of a new and simple formalism that resemble the Stroh formalism, solutions for multilayered plates are expressed in terms of the propagator matrix. The present solutions...

in this paper, the free vibration response of a laminated composite rectangularplate supporting a rotating circular patch mass is studied. the two variable refined platetheory that employs only two unknown functions as against three in the case of simpleshear deformation theory is applied to define the third order displacement field of acomposite rectangular plate. the plate is considered to ha...

An investigation into the dynamic characterisation of a rectangular flexible plate structure is presented and a simulation algorithm characterising the behaviour of the plate is developed using finite difference methods. A thin, rectangular plate, with all edges clamped, is considered. The investigation is accomplished by varying the width over the length ratio of the plate. The algorithm is im...

This paper presents a new configuration for semi-supported steel plate shear walls to increase their efficiency. For this purpose, the infill is proposed be trapezoidal shape instead of rectangular one. To find most efficient inclination angle lateral sides, numerical parametric study was conducted. Five different values including 60, 75, 90, 105, and 120 degrees were considered. Furthermore, t...

The periodic flexural-gravity waves propagating along a frozen channel are investigated. has rectangular cross section. fluid in the is inviscid, incompressible and covered with ice. ice modeled by thin elastic plate whose thickness varies linearly. Two cases have been considered: symmetrically across channel, being smallest at center of largest walls; from value one wall to another wall. 2D pr...
