“…To overcome the limitation in using conventional tools in fatigue life prediction under the multiaxial load, Bannantine and Socle proposed to use the rainflow method to either count the normal strain or the shear strain individually on the critical plane [16]. e critical plane is where the actual crack and fracture initiate and propagate [17][18][19]. Wang and Brown suggested using von Mises strain as the indicator for rainflow counting, and the time series need further manipulation before rainflow count [20].…”

Fatigue life prediction is an important part of the reliability and durability analysis of automobile components. Based on Wang and Brown’s framework, multiaxial random fatigue damage was adopted to predict the fatigue life of half-shaft. The stress analysis of half-shaft was resolved analytically to determine the local stress tensor in the potential area of fracture. The maximum shear strain fatigue damage parameter and the normal stress fatigue damage parameter were evaluated to predict the fatigue life of half-shaft. The results show that the prediction method is reliable and meets the service life and safety requirements.
