The FG sandwich plates are subjected to transverse mechanical and hygrothermal sinusoidal loads. The present sandwich plate is composed of a homogeneous ceramic core covered by two FG layers. The properties of face layers are graded according to a power law distribution in terms of volume fraction. The present thesis contains three chapters as follows: Chapter one presents tenThesis
