A Novel Method to Predict the Low-Cycle Fatigue Life

Since fatigue failure commonly occurs in mechanical equipment, the prediction of the fatigue life is important to ensure safety in the running cycle of production. In this paper, a method is proposed to predict the low-cycle fatigue life. The accuracy of the proposed method is compared to the strain energy criterion and Coffin–Manson/Basquin equation with three different materials. The results indicate that accuracy of the proposed method is similar to the strain energy criterion and Coffin–Manson/Basquin equation in predicting the low-cycle fatigue life.
