Abstract
The paper presents the results of low-cycle fatigue tests on P91 steel specimens, carried out under constant strain and constant stress conditions, in several test temperatures. The analysis of the experimental data indicates the influence of fatigue testing conditions on the fatigue life predictions based on the Ramberg-Osgood relationship, while the increasing test temperature enhances the differences. In the next stage of the research the constitutive description of low cycle fatigue behavior of P91 steel is developed within the framework of thermodynamics of irreversible processes with internal state variables. The entropy production based damage model is applied to reflect the fatigue softening. The model is implemented into a numerical subroutine, and identified on the basis of the experimental data. A good agreement is obtained between simulations and experiment.
