Abstract
A further comprehensive detailed nonlinear theoretical model of asymmetric anisotropic doubly curved laminated composite sandwich plates and shells considering the case for the transversely compressible core in sufficient detail, thereby capturing the wrinkling phenomenon of the sandwich panel, is presented. The theory assumes a transversal displacement of the core in terms of a second-order power series expansion, thus theory two. The governing equations are developed by way of an energy approach known as Hamilton’s principle. Finally, an application of the governing equations with regard to buckling and postbuckling is provided to demonstrate the solution approach to these equations through the use of the extended Galerkin method.
