Stability of Shell-Stiffened and Axisymmetrically Loaded Annular Plates

Abstract

The present paper is concerned with the stability problems of a solid circular plate and some annular plates each stiffened by a cylindrical shell on the external boundary. Assuming an axisymmetric dead load and axisymmetric deformations we determine the critical load in order to clarify what effect the stiffening shell has on the critical load.
