摘要：

The Ritz method with algebraic polynomial displacement functions is used to solve the vibration problem for laminated composite plates having different boundary conditions. Natural frequencies and mode shapes for plates having two adjacent free edges and the remaining edges either simply supported, clamped or free are presented. Convergence studies are made which demonstrate that accurate results are obtained by using 64 displacement terms for symmetrically-laminated plates. The effects of various parameters (material, fiber orientation and boundary conditions) upon the natural frequencies and mode shapes are studied.
