The object of this investigation is to determine if and how the presence of core materials, flexible in shear, affects the magnitude of variation of the stresses and deflection in orthotropic sandwich plates. The differential equations for an orthotropic sandwich plate are derived by a variational m

โฆ Synopsis
The displacement response of randomly excited simply supported orthotropic sandwich plates is investigated analytically. The source of random excitation is assumed to be an ideal white noise uniformly distributed over the plate. The mean square response of the displacement is computed for variation of various non-dimensional parameters: namely, 9 the damping ratio, the core shear stiffness, the core orthotropy, the face orthotropy and the aspect ratio. The results obtained are shown graphically and discussed.

In this paper, the orthotropic sandwich plates having orthotropic faces and core, unequal face thicknesses and dissimilarities in face materials (including different Poisson ratios for facings) are considered. The stress-strain relations and differential equations are derived for bending of such pla
A system of three non-linear partial differential equations, defining the finite amplitude free and forced vibrations of orthotropic multi-layer sandwich plates, is developed by using variational principles. The simultaneous equations involve the transverse deflections, a membrane stress function, a
