“…Ghayesh et al (2017) studied the amplitude frequency characteristics of imperfect FGM microplates with an initial sinusoidal curvature. Azarboni et al (2016) investigated how the excitation frequency affects the pulse buckling of plates with imperfection. Using an analytical method and the first-order theory, Huy Bich et al (2014) investigated the nonlinear vibration of a small sine-type imperfect shallow shell.…”

In this article, the natural vibration investigation of a functionally graded material sandwich plate with initial geometrical imperfection of the exponential function is conducted. Two face sheets of the sandwich plate are composited by functionally graded material. Their material coefficients are affected by temperature and vary in the direction of thickness following the power law. The core layer is only the metal. With the aid of Reddy’s displacement fields, a quasi-three-dimensional model is used, in which the effects of transverse stretching on natural vibration are considered. The natural frequencies and model shapes of the system are calculated on the basis of Rayleigh–Ritz method and Chebyshev polynomials. A comparison of these results with those of the existing three-dimensional theory results shows the validity and computability of present method. The influences of various parameters on the natural frequencies are researched in detail.
