Fiber reinforced composite plates are often highly stressed structures. For an efficient design of such plates interlaminar stresses have to be evaluated as precisely as possible. In this paper we propose a finite element formulation for the analysis of transverse shear stresses in layered composite plates. For this purpose the equilibrium equations are exploited with appropriate shape functions in weak form which leads to a local discrete boundary value problem. Two different models to compute the derivatives of the strains are considered. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
