The effects of through-the-thickness shearing strain energy on the geometric non-linear behavior of thin and relatively thick rectangular functionally graded plates are studied in this paper. It is assumed that the mechanical properties of the plates, graded through the thickness, are described by a simple power law distribution in terms of the volume fractions of constituents. The plates are assumed to be under lateral pressure loads. The fundamental equations for rectangular plates of FGM are obtained using the classical laminated plate theory (CLPT), first order shear deformation theory (FSDT) and higher order shear deformation theory (HSDT) for large deflection and the solution is obtained by minimization of the total potential energy.
