To the calculation of the toroidal shell with a local deepening on the external and on the inner surface

Thin-walled toroidal shells are widely used in the construction During operation, various defects appear on surface of shells, particular, local depressions outer and inner surfaces, causing stress concentration structure. A three-dimensional spline option finite element method was developed to determine stress-strain state a shell with deepening surface. The numerical experiments were carried out. regularities changes change geometric parameters noted.
