| Abstract: | A technique for analysis of the nonaxisymmetric thermoelastoplastic stress-strain state of laminated circular cylindrical
shells is developed. It is assumed that the layers in a laminated package do not slip and separate relative to each other.
The problem is solved using the geometrically linear theory of shells that is based on the Kirchhoff-Love hypotheses. The
equations of thermoplasticity are written in the form of the method of additional strains. The order of the obtained system
of partial differential equations is reduced with the help of trigonometric series in the cyclic coordinate. The systems of
ordinary differential equations thus obtained are solved by Godunov's method of discrete orthogonalization. As an example,
the nonaxisymmetric thermoelastoplastic stress-strain state of a two-layer cylindrical shell is considered.
