Abstract
The conditions for predicting the behavior of thin-walled cylinders of metallic isotropic materials loaded by internal pressure and axial tensile force are presented in the article. The area of large plastic deformation was investigated, and the corresponding incompressibility condition was used. Elastic deformations were neglected. The maximum load conditions were used to derive the relationship between the residual relative deformations and the true stresses at the time the strain was localized. Influence of stress state and parameters of thin-walled tube geometry on the value of limit true stresses and residual deformations is investigated. A graphical analysis of the obtained conditions was carried out.
