摘要 从总循环应变能的角度出发,提出了一个新的疲劳寿命计算模型,通过对30CrMnSiA钢和AISI4340钢两种材料的的疲劳寿命计算,并与相关实验数据对比,证明了该模型计算疲劳寿命较为准确. Based on the concept of the total cyclic strain energy, a new model is developed to predict the fatigue life of materials. Its validity is tested by comparing the calculated results and testing data for 30CrMnSiA and AISI 4340 steels
