In this paper, the analytical solution is presented for nonlinear bending response of functionally graded porous (FGP) plates based on first-order shear deformation theory. The neutral surface position and three patterns of porosity distributions namely uniform, non-uniform symmetric and non-uniform non-symmetric are considered. Using displacement approach in conjunction with Galerkin method, the analytical solution is obtained for various boundary conditions. The numerical examples are performed and compared with those available in the literature to show the accuracy of the present results. The effects of porosity distribution patterns and porosity coefficient, an aspect ratio of plates, Pasternak elastic foundation parameters, and boundary conditions on deflection, stress resultants of FGP plate are investigated
