The study introduces a model of elastoplastic deformation of structural alloys under conditions of complex nonisothermal loading. The model is based on the plastic flow theory. Within the research we derived the relations that made it possible to determine the parameters of the model using the results of sample tests according to the program of rigid symmetric cyclic deformation. Moreover, we developed an algorithm for determining the plasticity parameters from a limited set of experimental data. Based on the algorithm developed, we obtained the plasticity parameters for the nickel alloy IN738LC over a wide temperature range.
Keywords: plasticity, complex deformation, parameter determination.
