Abstract: In this paper, fundamental equations and boundary conditions of the nonlinear bending theory for a rectangular sandwicl slate with a soft core are derived by means of the method of calculus of variations.Then the nonlinear bending for a simply supported rectangular sandwich plate under the uniform lateral load is investigated by use of the perturbation method and a quite accurate analytic solution is obtained.

Key words: rectangular sandwich plate, nonlinear bending
