The Bending of Symmetrical Laminated Composite Plate Based on Symplectic Method

摘要：

This paper applies a symplectic method to study analytically the stress distributions of Composite laminated plates. Using variation principle and introducing separation of variables, dual equations were presented. Then in the symplectic space which consists of the original variables and their dual variables,the problem can be solved via effective mathematical physics methods such as the method of sepatation of variables and eigenfunction vector expansion. The transcendental equation and eigenvector are deduced. The results of cross-ply and angle-ply laminated graphite-epoxy composite plate are shown, which is compared with established results. The parameters influences on mechanical property are also discussed.
