abstract
A layer-wise theory proposed by the author is reviewed and its applications to bending of laminated composite plates and buckling of circular cylindrical composite shells is presented. The layer-wise theory accounts for 3-D kinematics and state of stress, and its formulation allows efficient calculation of stresses and buckling loads compared to the 3-D elasticity formulation of laminated composite structures. Results of the displacement finite element analysis for bending of laminated plates and the Navier solution for buckling of stiffened cylindrical shells are discussed.
