Abstract
It was proposed methodology of determining parameters of model of nonisothermal cyclic stress-strain curve. Algorithm of pattern recognition was implemented. It was based on minimization of function of mismatch between experimental results and calculation of three-parameter model curve which depends on Bauchinger’s effect, elastic unloading modulus and scale of transformation of nonlinear part of stress-strain curve. Odkvist’s parameter was used for measure of plastic deformation. Simulation of cyclic stress strain curve was carried out. Results of simulation were compared with experimental data.
