Exact analysis of layered plates using mixed form of hooke’s law

Abstract

Recent applications of composite materials involve the use of thick-section layered and/or sandwich construction. The complexities of composite materials demand extensive analysis techniques to predict the reliable response of even the simplest of loading conditions. Various theories have been developed for exact analysis of laminated composite plates. The present analysis of laminated plate is based on Mixed Form of Hooke’s Law. This approach leads one to write the boundary conditions on the top and bottom surfaces of the plate directly in terms of transverse stresses. The advantage of this theory is that equilibrium conditions and other boundary conditions can be enforced in a simplistic manner so that realistic behavior of layered plates can be predicted.
