After tensile character testing for pure winding fatigue damage samples at three different stress level, the relationship of energy degradation and fatigue damage has been studied for 45 steel. It is shown that the variable of energy degradation is sensitive to damage. So, a new damage variable that is energy degradation has been put in this paper, it is simple and effective for damage analysis and valuable for engineering using.
