Abstract To study the influence of the body rheology on its stress-strain state under the action of temperature, the A.N. Sporykhin model (hardening elastoviscoplastic body) is used. Quasi-static deformation is assumed in the absence of mass and surface forces. For this formulation of the problem, the components of stresses and displacements in the elastic and plastic regions, the zone of unloading and repeated plasticity are determined, and their dependence on taking into account specific rheological features of the body is studied.
