| Abstract: | A technique is developed for determination of the axisymmetric thermoelastoplastic stress-strain state of branched laminated
transversally isotropic shells of revolution under loads that cause the meridional stress state and torsion. The method is
based on the rectilinear-element hypotheses for the whole package of layers. To describe the processes of active elastoplastic
deformation of a transversally isotropic material, deformation-type equations, which are constructed without recourse to the
plastic-potential existence condition, are used. The scalar functions in the constitutive equations depend on the shear-strain
rate and temperature. The solution of the problem is reduced to numerical integration of systems of differential equations.
An example of determination of the elastoplastic state of a two-layer cylindrical shell stiffened with a rigid ring support
is presented.
