3. Ó¢£ºA, B, C, D and E are five commonly used accumulative damage models in the multiaxial accumulative fatigue damage calculation. Therefore, for sake of comparison, they are also selected in this paper to calculate the accumulative fatigue damage sum. The five models are briefly reviewed in the following.
