Abstract

Abstract

The scatter of fatigue life is a factor considered for fitting lab-test fatigue life curves.By leading into diversity coefficient CR,the rule of selection of method to fit lab-test fatigue life curve was established with the value of maximum CR correspond to kinds of S/N the experiment used.Lab-test fatigue life data was fitted to curves according to the rule,and it indicates that the rule can improve the curve fitting.
