Thermoelastoplastic nonaxisymmetric stress-strain analysis of laminated shells of revolution

A technique for nonaxisymmetric thermoelastoplastic stress-strain analysis of laminated shells of revolution is developed. It is assumed that there is no slippage and the layers are not separated. The problem is solved using the geometrically linear theory of shells based on the Kirchhoff-Love hypotheses. The thermoplastic relations are written down in the form of the method of elastic solutions. The order of the system of partial differential equations obtained is reduced by means of trigonometric series in the circumferential coordinate. The systems of ordinary differential equations thus obtained are solved by Godunov's discrete-orthogonalization method. The nonaxisymmetric thermoelastoplastic stress-strain state of a two-layered shell is analyzed as an example.
