Abstract

In this article, the vibration and nonlinear dynamic response of imperfect advanced sandwich nanocomposite plate subjected to uniformly distributed pressure has been studied using fourth-order Runge–Kutta and Galerkin methods. The composites are assumed to be made of a gold layer, an auxetic layer, and a piezoelectric layer. Detailed parametric studies to evaluate the effects of the geometrical dimensions, the thickness of layers, imperfections and mechanical loads on the nonlinear dynamic response and natural frequency of advanced multilayer nanocomposite plates are discussed. The accuracy of the present results is validated by comparing with others from literature.
