Resumen:
This paper presents the formulation of an enriched macro finite element based on theTrigonometric Shear Deformation Theory for the static analysis of symmetrically laminatedcomposite plates. Shear correction factor is not required because this theory accounts fortangential 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 asenrichment functions. The implementation of the obtained algorithm is simple and efficient, and allows studying general quadrilateral plates with a single macro element. Several examples are presented to show the capability and applicability of the developed formulation
