“…Besides, many materials show cyclic hardening or cyclic softening behaviour under cyclic loading, which may cause the variation in plastic strain range. It was reported that the variation of hysteresis energy density (HED) was relatively small throughout the fatigue process under high temperature even cyclic hardening occurs 21,22 . Hence, the energy‐based approach shows a good promising in bridging the life prediction and physical mechanism, and it can be an alternative to strain‐based methods.…”

“…Though these methods can account for the loading waveform effect, the damage interaction diagram, which is very crucial in the design and safety assessment of high-temperature structures, cannot be established. Since experiments and theory [20,21] have revealed that a stable value of hysteresis energy is arrived after a short initial cycle, even the materials possess the cyclic hardening or softening behavior, many energy-based fatigue life prediction methods have been proposed, and good prediction accuracy is obtained [22][23][24][25][26][27][28]. For example, Wang et al [26,27] proposed a modified strain energy density exhaustion model for creep-fatigue life prediction in which the mean stress effect is considered.…”
