A microstructure-based numerical approach for uniaxial fatigue life-based non-uniaxial fatigue life prediction of hypo-eutectoid steels by Jonghoon Shin, Hyunki Kim, Minwoo Kang, Chungan Lee, Seunghyun Hong, Yoon Suk Choi

“…A numerical methodology was proposed for the microstructure-based prediction of the non-uniaxial fatigue life using the fatigue life prediction model calibrated only by the uniaxial fatigue life data for 44MnSiVS6 hypo-eutectoid steel. The proposed prediction procedure involves the generation of a statistically representative synthetic microstructure, the development of slip system-based fatigue constitutive models for the primary ferrite and pearlite phases constituting the hypo-eutectoid steel, the synthetic microstructure-based finite element simulations for uniaxial, torsional, and in-phase and out-of-phase axial plus torsional fatigue loading conditions using the developed constitutive models, the extraction of the cyclic increment of the fatigue indicator parameters (ΔFIP) from fatigue-simulated microstructures for the local fatigue damage quantification, the calibration of the uniaxial fatigue life prediction model by linking simulated uniaxial ΔFIPs to the uniaxial fatigue life data, and finally the prediction of the non-uniaxial fatigue life (through simulated non-uniaxial ΔFIPs) using the uniaxial fatigue-calibrated life prediction model. …”
