Abstract: Multi-scale fatigue model and image-based simulation method are developed in this study to describe collective short cracks evolution process in micro-scale and continuous fatigue damage evolution in macro-scale based on the concept of continuum damage mechanics (CDM). The relationship between the micro-scale and macro-scale fatigue is explored to enhance the understanding the nature of fatigue phenomenon. A case study is carried out to verify the developed multi-scale fatigue model and image-based simulation method. The results show that it is more effective and clear to reveal metal fatigue failure mechanisms from the viewpoint of multi-scale.
