NONLINEAR ANALYSIS OF CORRUGATED ANNULAR PLATES UNDER COMPOUND LOAD

Abstract

This paper is a continuation of the author's previous papers~([1,2]).Based on the nonlinear bending theory of orthotropic circular plates, the nonlinear bending of a corrugated annular plate with a nondeformable rigid body at the center has been investigated under the combined action of uniform pressure and a single concentrated load at the center, For two kinds of outer edges, namely, rigidly and loosely clamped edges, analytical solutions of the plate have been obtained by the modified iteration method. As a particular example, a toothed corrugated annular plate with a nondeformable rigid body at the center and a rigidly clamped outer edge under the pressure uniformly distributed over the surfaces of the plate and the body has been considered. Numerical results obtained have been compared with the theoretical and the experimental results given by Andryewa~([3]). The present formulas have been shown with high accuracy.
