| Abstract: | Based on the Reissner Mindlin plate theory considering the first order shear deformation effect and including the plate foundation interaction, a nonlinear bending response of a rectangular thick plate with four free edges subjected to transverse partially distributed loads and resting on a two parameter elastic foundation has been studied by a mixed Galerkin perturbation method. The solutions satisfy all bounday conditions and governing equations. The influence played by the foundation stiffness is also discussed. |
