摘要	The concept of equilibrium in crack numerical density is applied to analyze the process of collective damage evolution for short fatigue cracks. The damage moments with respect to crack numerical density and crack length are adopted to evaluate the damage extent of dispersive short cracks. The analytical results show that the crack growth rate is in relation to the "zero-th" order of damage moment D-0, and the "first" order of damage moment D-1 increases exponentially with fatigue cycles whereas (D) over dot(1) is linearly proportional to D-1.
