Abstract
Abstract The analytical closed-form solution providing the value of fundamental frequency of the CCCF composite sandwich plate is proposed in this article. The variational equations of motion are derived using Hamilton’s principle in conjunction with the first-order shear deformation theory. The solution approach involves reduction of the governing equations of motion to a system of ordinary equations using Kantorovich procedure and subsequent application of the generalised Galerkin method. The analytical solution is verified using the finite element modal analysis. The comparisons of computational results have shown that the fundamental frequency of the CCCF sandwich plates can be calculated with sufficient accuracy using the analytical technique developed in this work.
