... model. Multiple high-cycle fatigue life prediction criteria were combined for life assessment and comparative analysis. The calculation results show that the calculated life based on the critical surface method is lower than that based on material mechanics, indicating that the calculation results...

... F np by utilizing a multi-axial fatigue life prediction approach based on the modified Wöhler curve method. Different from the hypothesis of previous integral models for computing factor F np where the loading path is considered uniform, a new model using an inhomogeneous integral is presented...
