LINEAR STATIC ANALYSIS OF LAMINATED COMPOSITE PLATES WITH LAYERWISE FINITE ELEMENT

Abstract

This article is about a layerwise finite element which is developed for the linear static analysis of laminated composite plates. In the first part; the paper presents a review of the literature involving the available theories and their drawbacks for multilayered composite plates. A second part reviews a relevant keypoint (zig-zag form of the displacement field in the thickness direction) that should be considered for an accurate stress and strain field. In the third part, the paper explains the layerwise finite element and the derivation of its stiffness matrix. The final part of the paper is devoted to giving a comparison of selected results that can be acquired either by layerwise finite element(Genson) or the other available theories in the literature.
