In this study, the nonlinear dynamic behaviour of a laminated plate is investigated. The thickness of the plate is varying parabolically in both directions and the plate is simply supported. In-plane stiffness and inertia effects are considered. The geometric nonlinearity effects are taken into account by using the von Karman large deflection theory of thin plates. The equations of motions for the plate are derived by the use of the virtual work principle. The displacement-time and strain-time histories are obtained and compared with the finite element results. The results are found to be in an agreement.
