NONLINEAR STATIC ANALYSIS OF MODERATELY THICK RECTANGULAR PLATE CONSIDERING THE COUPLED EFFECT OF ELASTIC FOUNDATION

In this paper, the nonlinear governing equations of moderately thick plate resting on two-parameter foundation including transverse shear deformation and coupled effect of the foundation are derived. By using of Galerkin method, the nonlinear bending behavior of moderately thick rectangular plate with four free edges on two-parameter foundation is analyzed. The effects of different parameters of the system on static bending are considered.
