Abstract

A three-dimensional spline option of the finite element method was developed to determine the stress-strain state of a toroidal shell with a local deepening on the inner surface. The numerical experiments were carried out, the regularities of the changes in a stress-strain state of the shell with the change in the geometric parameters of the deepening were noted.
