This article presents the formulation of a new enriched plate macro element.This formulation is based on the First Order Shear Deformation Theory (FSDT) with the incorporation of new parameters. These parameters are calculated by compatibility of FSDT displacement and various Higher Order Shear Deformation Theories (HSDT) displacements. In this way, an approximation C0 is obtained. Shear correction factor is not required because this HSD theories account for tangential stress-free boundary conditions on the plate boundary surfaces. The macro element is obtained using the principle of virtual work and Gram-Schmidt orthogonal polynomials as enrichment functions. Several examples corresponding to the static and dynamic analysis of symmetrically laminated composite plates are presented to show the capability of the developed formulation.
