| Abstract: | The fatigue life for components can be predicted by plot method which is easy and convenient for engineering application. Based on the usual fatigue life prediction formula, a new formula for estimating the low stress and high cycle fatigue life adopting more accurate S N curve relationship. Weibull S N curve formula is proposed and deduced. The solution of the new formula is given, too. In addition, an example has been calculated and proved in practice. The results of the new formula and the old one are given and compared. |
