Implementation of interacting creep and fatigue under thermo-mechanical loading

Original language description

Presented work is dealt with thermo-mechanical fatigue analysis. Only elastic stress and temperature field are taken from FEM analysis. Strain components are calculated using nonlinear Maxwell model to cover both elastoplasticity and viscoplasticity. For stepwise stress history elastoplastic and viscoplastic strain component are gain independently solving one after another. For every point in loading history is consequently found closed hysteresis loop and damage increment corresponding to actual hysteresis loop is evaluated. Current damage is calculated by Prandtl-Ishlinskii model of hysteresis using iso-thermal fatigue curves.
