| Abstract: | This paper presents a new expression method for P-S-N curve. As an example,the fatigue test data of 16Mn rolled steel is used to achieve the empirical formula for this method and its accuracy is satisfying. At the end,we discuss its engineering significance to simplyfying fatigue test in order to obtain P-S-N curve of parts. |
