Nonlinear bending of circular sandwich plates
Fundamental equations and boundary conditions of nonlinear axisymmetrical bending theory for circular sandwich plates with a soft core are derived by means of variational methods. Especially in the case of very thin faces, the preceding fundamental equations and boundary conditions are considerably simplified. For example, a circular sandwich plate with edges clamped but free to slip under the action of uniform lateral loads is considered. A more accurate solution of this problem has been obtained by means of the modified iteration method.
