| Abstract: | In this paper,free vibrations of laminated rectangular plate which has arbitrary plies and liad-angles formed by fibres are analyzed.A three-dimensional elastic analysis method is introduced for determining the natural frequencies of orders and the correspondent oscillation modes of laminated anisotropic rectangular plate.The plate is made of multi-ply reinforced fibre materials,the fibres of each ply are laid at arbitrary angles with the edges of the plate,the number and thickness of plies as well as the dimensions of the plate can be arbitrary.The boundary conditions of plate edges can be arbitrary combinations of clamped,simple-supported,and free.Some numerical results are presented. |
