Abstract
The solution of the buckling problem for a rectangular composite sandwich plate with two parallel simply supported edges and another two edges clamped (SSCC) is presented in the paper. The plate is composed of two identical composite facings and orthotropic core, and subjected to in-plane uniform compressive load applied to the simply supported edges. Buckling equations are derived based on the first-order shear deformation theory. The problem is solved using the Levy and Galerkin methods. The analytical formula for the critical load has been obtained and verified using finite-element analysis. The design analyses have been performed for the sandwich panels subject to constraints imposed on the value of buckling load.
