摘要：

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.
