Abstract
An approximate solution procedure is presented for rectangular orthotropic sandwich plates under general boundary conditions. A variational method is used to reduce the partial differential equations to a set of ordinary differential equations, which are then solved by numerical integration. The method is used to obtain solutions for a sandwich plate with clamped boundaries. The results from the method compare favorably with existing solutions. A series of graphs suitable for design purposes is presented depicting the variation of the maximum values of the bending moments, shear forces and deflections in square sandwich plates with orthotropic cores for different shear stiffnesses.
