Abstract
A current structures complication in Functionally Graded Materials FGM is the analysis of the distribution of the displacement and thermal stresses in the original thickness. The interest of this study is the analysis of thermoelastic behavior of the bending of sandwich plates FGM using third-order plates of travel theories (TSDPT) and sinusoidal theory (SSDPT). In this article we use a type of sandwich plate FGM «Type: Metal / Ceramic / Metal» composite materials. It is assumed that the material properties and the coefficient of thermal expansion of the plate vary continuously in the thickness direction according to a simple power law distribution function of the volume fraction of the components. We can say that the proposed theory is accurate and simple to solve the thermoelastic behavior of the bending of FGM sandwich plates.
