Modeling of cyclic thermo-elastic-plastic behaviour of P91 steel
has been extensively investigated. The constitutive model of Armstrong-Frederick,
extended with temperature rate effects, has been applied to describe the behaviour of the
thermo-elastic-plastic material. The proposed model has been successfully implemented in
simulation of low cycle fatigue of the examined steel in two different temperatures.
