The typical fatigue process is to maintain stress / strain levels below the allowable for the required number of cycles.
Multiple loads often occur and will have a different cycle requirement. Ansys Fatigue, or the more advanced nCODE can predict the component life. An alternative approach is to understand that a crack exists in the component. The crack is analyzed to determine whether it will propagate, and if so, at what rate.
