Abstract

Abstract

In this paper,the cyclic plastic strain energy is acted as damage variable and its mathematical model of transient response is established.The nonlinear fatigue damage function is given by means of the damage mechanical method.The formula used for prediction of low cyclic fatigue life is obtained from this damage function which takes into account the cyclic relativity of cyclic plastic strain energy.The low cyclic fatigue life predicted by this formula is in correspondence with the experimental result.
- cyclic plastic strain energy,
- fatigue damage,
- life prediction
