Analysis of the thermoelastoplastic nonaxisymmetric stress-strain state of laminated circular cylindrical shells (Q2782093)

The authors develop a method for determination of nonaxisymmetric thermoelastoplastic stressed-strained state of laminated circular cylindrical shells. The laminated package is assumed to work without mutual sliding and separation of the layers. The problem is solved by means of the geometrically linear shell theory which is based on Kirchhoff-Love hypotheses. The thermoplasticity correlations are written by using the method of additional strains. The order of the obtained system of partial differential equations is reduced by employing the trigonometric series in angular coordinate. The systems of ordinary differential equations obtained so far are solved by Godunov's method of discrete orthogonalization. As an example, nonaxisymmetric thermoelastoplastic stressed-strained state of two-layer cylindrical shell is considered.
