Abstract

The elastoplastic stress-strain state of cylindrical shells weakened by a curvilinear (circular) hole is investigated. Numerical results are given for shells with a reinforced hole under the action of an internal pressure of specified intensity. The influence of the geometric parameters of the shell on the stress distribution in the concentration zone is investigated in the elastic and inelastic stages of deformation. The variation in flexure along the hole contour is given for linear and nonlinear problems, and the distribution of the maximum stress-concentration coefficients is also given for various geometric parameters.
