Elasto-plastic stress and strain are calculated with temperature dependent hysteresis model of stabilized stress-strain relation. Generalized Prandtl-Ishlinskii model is used for this purpose. For every point in loading history is found closed hysteresis loop. Damage for damage parameter corresponding to current hysteresis loop is evaluated by using PrandtlIshlinskii model. This procedure was implemented and applied to the generator turbine.
