Abstract
The study presents the results of low-cycle fatigue tests on P91 steel specimens. The tests were carried out under constant strain (εac=const) and constant stress (σa=const) conditions, at two temperatures (T=20 °C and T=600 °C) and five εac and σa levels. A comparative study of the test results was performed using analytical models to characterize fatigue in relation to the strain and energy. The analysis of the experimental results shows the effect of the fatigue testing conditions on the fatigue life predictions. Simplifications applied in the theoretical models which affect the final fatigue characteristics are discussed in detail. It is demonstrated that the analytical models using strain-based characteristics of fatigue do not reflect the actual test conditions at σa=const. The conclusions are confirmed by the analysis of the test results with the use of energy parameters of fatigue.
