Free Vibrations of Antisymmetric Angle-Ply Laminated Thin Square Composite Plates


Abstract: Numerical results are presented for vibration frequencies of antisymmetric angle-ply laminated thin square composite plates having different boundary conditions. Boundary conditions are chosen as 2 adjacent free edges and the remaining edges are simply supported, clamped, or free. The Ritz method, along with the displacement assumed in the form of simple polynomials, is applied to solve the problems. Convergence studies are presented to demonstrate the accuracy of the results. The effects of various parameters such as fibre orientation, number of layers, and boundary conditions upon the natural frequencies are studied.
