摘要：

A method for numerical analysis of the elastoplastic axisymmetric stress-strain state of thin shells undergoing nonisothermal deformation along paths of small curvature with allowance for secondary plastic strains and the third invariant of stress deviator is elaborated. The stress-strain state of a shell during heating and cooling is analyzed numerically.
