| Abstract: | On the basis of the L3 unit element proposed in the related literature, this paper presents an energy functional for geometrically nonlinear analysis of laminated composite plates and shells and related nonlinear finite element formulations. Incremental methods in terms of either applied load or displacement are discussed. Numerical examples are given to validate the proposed methods and satisfactory results are obtained. |
