摘要：
Accurate solutions for the free vibration eigenvalues of cross-ply laminated plates have been achieved by the traditional superposition method. It is shown that solutions can be obtained for any combination of clamped-simply supported boundary conditions. In this paper the modified superposition-Galerkin method is introduced for solving this family of problems. It is shown how this new approach leads to vast simplification in the computational procedure with the same accurate eigenvalues being obtained.
