According to the relationship between material fatigue performance curve and concerned parameters in fracture mechanics , the relationship between fatigue life and crack half length is obtained , that is equivalent crack length of fatigue life . the function relationships between these two aspects are constructed . the experiment data show that this method can express the same character of fatigue life of all kinds of materials and experiment data acquired from different materials can be used each other
通过材料力学疲劳性能曲线和断裂力学之间有关参量间的演变关系，得到了疲劳寿命与裂纹半长的关系，即疲劳寿命的折算裂纹长度，建立了两者之间的函数关系并利用这个函数关系说明了疲劳寿命的切线模量因子法，能反映各种材料疲劳寿命的共同变化规律，试验数据可在不同材料之间互相参考使用，具有重大意义。
