Nonlinear Vibration of Layered Composite Plates Including Transverse Shear and Rotatory Inertia

摘要

The large amplitude free flexural vibration of layered composite plates, incorporating the effects of transverse shear and rotatory inertia, is studied using a finite element based on the displacement field of a shear deformable theory and the strain-displacement equations of von Karman's plate theory. Free vibration of cross-ply and angle-ply rectangular plates is analyzed and natural frequencies are presented showing the effects of boundary conditions, side-to-thickness ratio (i.e. transverse shear), aspect ratio, orientation of layers and material anisotropy.
