摘要
A multi-scale fatigue damage evolution model is proposed for describing both the behaviour of short fatigue cracks nucleation and growth in micro-scale and fatigue damage evolution reflecting the progressive deterioration process of metal components and structures in macro-scale. The model is verified through the experimental data of fatigue damage. It was found that, the model can offer a new reasonable explanation of the effect of load sequence on fatigue life, and also can predict the fatigue life during fatigue damage accumulation due to short cracks nucleation and growth in metal components and structures.
