Abstract
This thesis is devoted to study the functionally graded materials (FGMs) plates resting on elastic foundations by using the simple first-order transverse shear deformation plate theory (SFPT) as well as the mixed first-order transverse shear deformation plate theory (MFPT). Some of the basic concepts of the theory of elasticity and FGMs are presented. The fundamental principles of elasticity theory such as equilibrium equations and Hooke’s law for different elastic materials are given. An introduction to the FGMs and elastic foundations is presented.
