摘要：

This paper, based on Lemaitre's potential of dissipation, derives a damaged evolution model for strain fatigue of ductile metals. Then the equation of fatigue-life prediction and the criterion of cumulative fatigue damage are deduced. Experiments for steel were conducted and the experiment data agreed with the model excellently. Thus the model can predict the damaged evolution during the strain fatigue process.
