A layerwise finite element formulation of a newly developed layerwise theory for the flexure of thick multilayered panels is presented. The displacement model accounts for non-linear and constant variation of in-plane and transverse displacement through the panel thickness. Reissner-Mindlin approach is used to model the faces of the sandwich structure. The displacement field for the core is modeled as quadratic function of the thickness coordinate.The three dimensional problem is reduced to the two-dimensional one by through-thickness integration of the strain energy. The discrete element chosen is a four-nodded quadrilateral with nine-degrees- of freedom per node (when shear continuity is imposed).An example problem is provided for awell-knowsandwich composite plate. The accuracy of the present code is ascertained by comparing it with various available results
in the literature.
