Abstract

This paper deals with the effects of initial geometric imperfections on nonlinear vibrations of antisymmetric angle-ply laminated plates. The nonlinear equations including the effects of imperfections, transverse shear deformation and rotary inertia are derived. A multi-mode solution is formulated for nonlinear vibrations of a simply-supported antisymmetric imperfect angle-ply plate. The modal equations are obtained by performing the Galerkin procedure and then solved by the Runge-Kutta method. It is found that the existence of geometric imperfections may result in a drastic change on the nonlinear vibration behavior. Numerical results are presented showing the effects of the amplitude of imperfection, side-to-thickness ratio, number of layers, lamination angle and material properties.
