| Abstracts: | Using the OpenFOAM numerical simulation environment, an algorithm for calculating the process of irreversible material deformation is implemented within the framework of the theory of temperature stresses, taking into account the connectedness of the temperature fields and plastic deformations. The three-dimensional problem of the irreversible deformation of an elastoplastic cylinder subjected to an unsteady thermal gradient is solved. The influence of the rate of change of the thermal field on the formation of the stress-strain state of the material is investigated.
