Abstract

This paper develops an improved model to estimate the effective material properties of functionally graded porous plates with evenly and unevenly distributed pores. Based on the higher-order shear deformation plate theory and extended von Kármán-type equations, dynamic equilibrium equations of the plate were built with the effect of the viscoelastic foundation. By using a two-step perturbation technique, the nonlinear frequency and dynamic response were obtain. The effects of the pore volume fraction, porosity distributions, and ceramic mass fraction were investigated.
