This paper presents the results of the calculation of a thin spherical shell, the material of which operates beyond the elastic limit. Thin isotropic shells of rotation of constant thickness h are considered. The complete system of the equations cont

Thin isotropic rotation shells of constant thickness taking into account the appearance of plastic deformations under the local loads are considered. The method of running with discrete orthogonalization is used for the numerical realisation of the p

In the present work the results of the study of plastic deformations distribution in the thickness in ring spherical shells are presented. Resolving differential equations system is based on the Hirchhoff-Lave hypothesis, linear thin shells theory an

The paper focuses on the model of calculation of thin isotropic shells beyond the elastic limit. The determination of the stress-strain state of thin shells is based on the small elastic-plastic deformations theory and the elastic solutions method. I

The problem of static analysis of a circular cylindrical shell located on the elastic base of the Winkler and reinforced by longitudinal ribs is considered. The stiffeners have a rectangular cross section. The external action is represented by forces

The paper focuses on the method of calculation of evolution shells beyond the elastic limit. The conclusion of the basic system of differential equations is based on the linear shell theory with regard to the Hirchhoff-Lave hypothesis and on the phys
