Abstract

Maximum loads for toruslike shells with constant thickness loaded with an axial force, internal pressure, and a bending torque are calculated. The rigid plastic body model, the Tresca yield condition, and the plastic yield law associated with it are used. Application of the finite element method for calculation of the maximum load on a shell is considered. A significant increase in the characteristic deformation of a shell is used as a criterion. The corresponding formulas for maximum loads are obtained based on the kinematic method of the limit equilibrium theory. The difference between the obtained results and the static solution does not exceed 3%.
