ABSTRACT The Palmgren–Miner rule is generally used for predicting high‐cycle fatigue (HCF) life under variable amplitude loading (VAL); however, it does not consider the effects of loading sequences, resulting in significant errors. Therefore, a new model was proposed in the present work that takes the impacts of loading sequences into consideration. The proposed model constructed a new damage transfer characteristic variable based on the intrinsic damage dissipation theory to characterize material damage conditions and effectively compensated for intrinsic damage dissipation, thereby addressing its application limitations in HCF life prediction under VAL. Based on previous literature and experimental data, a residual fatigue life prediction model under two‐stage and multistage block loading, variable cyclic loading, and corrosive environments was presented, and its prediction ability outperformed those of the Palmgren–Miner rule and newer models proposed in recent years.
