Vibration, Buckling and Dynamic Stability of a Symmetrically Laminated Anisotropic Rectangular Plate

摘要

Vibration, buckling and dynamic stability of a symmetrically laminated anisotropic rectangular plate are reported for various boundary conditions, fiber orientations of laminas and configuration of a laminate in this paper. This problem is solved by using a Galerkin method and the harmonic balance method. At first, vibration and buckling properties are shown for three different materials, various boundary conditions and fiber orientations. Then, dynamic unstable regions of a symmetrically laminated square plate are obtained and compared with that of a isotropic square plate.
