| Abstract: | In this paper, a revised mathematical model of the transient response of the cyclic plastic strain energy was used to establish a new criterion for low cyclic fatigue failure. A formula used for the estimation of low cyclic fatigue life was given from this criterion, the rationality and efficacy of the new criterion were verified by means of a low cyclic fatigue test. |
