Modelling of thermo-mechanical fatigue on engine generator turbine
Original language description
Presented paper is dealt with thermo-mechanical fatigue analysis of the generator turbine. Only elastic stress and temperature field are taken from FEM analysis. 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 Prandtl-Ishlinskii model. This procedure was implemented and applied to the generator turbine.
