Strength of Materials Aims and scope

Abstract

The basic equations and numerical results of investigations of the stress — strain state of a cylinder near a stiffened circular cutout are presented. The influence of nonlinear factors on the stress distribution near the cutout is studied as a function of the stiffness of the stiffeners on the basis of a numerical solution of different variants of nonlinear and linear problems. The most suitable parameters of a stiffening element are determined for a cylinder under prescribed internal pressure.
