Determination of Contact Fatigue P-S-N Curve of a Super-hard Stainless Steel

摘要: 测定某超硬不锈钢的接触疲劳P-S-N曲线,估计出试验应力S与试样寿命N之间函数关系式N=CS^-m中的待定参数C和m,得出不同破坏概率(1%,5%,10%,50%)下试验应力S与寿命N的关系,为材料的使用和产品设计提供试验依据。

Abstract: The contact fatigue P-S-N curve of a kind of super-hard stainless steel is determined, and the parameter C and m in the formula of N=CS^-m is estimated. The relationship between test stress S and life span N under different failure probabilities (1%, 5%, 10%, 50%) is obtained, which provide basis for the application of the material and the relative product design.
