An improved model to simulate the effective material properties of functionally graded porous plates

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.
