  • In this paper, fundamental equations and boundary conditions of nonlinear axisymmetrical bending theory for the circular sandwich plates with a soft core are derived by means of the method of calculus of variations. Especially in the case of very thin faces, the preceding fundamental epuations and boundary conditions simplity considerably. For example, a circular sandwich plate with edge clamped but free to slip under the action of uniform lateral load is considered. A more accurate solution of this problem has been obtained by means of the modified iteration method.All results are presented in figures which are ready for direct application.
