摘要
给出了一种描述ε-N曲线的三参数幂函数公式,与著名的Manson-Coffin公式相比,它能更好地拟合各种材料的应变-寿命试验数据,并且可以更方便地用于计算结构的损伤和寿命。
A formula of three-parameter power function for strain-life fatigue curves is presented in this paper. Fatigue limits of materials are considered in the formula. Therefore it can fit strain-life data better than the Manson-Coffin formula. Many fatigue results of materials have satisfactorily been treated by this formula. It is simple and convenient for calculating life and damage of structures.
