Recently, the authors proposed the simple idea that Gaßner curves can be interpreted as shifted Wöhler curves if the Palmgren‐Miner rule is applied. The idea is extended here to the general case of nonzero mean stress fatigue loading applied to smooth or notched specimens. The mean stress effect has been addressed through the corrections proposed by Smith‐Watson‐Topper and by Walker. In this way, a new expression for the shift factor G has been obtained. Through the application of the theory of the critical distances in its point variant, G is demonstrated to be valid for both smooth and notched geometries. A comparison with the Society of Automotive Engineers (SAE) Keyhole test program data is added to substantiate the findings.

Gaßner曲线上的平均应力影响被解释为移动的Wöhler曲线，并应用于平滑且有缺口的几何形状

最近，作者提出了一个简单的想法，即如果应用Palmgren-Miner规则，Gaßner曲线可以解释为移动的Wöhler曲线。这里的想法扩展到了非零平均应力疲劳载荷应用于光滑或缺口试样的一般情况。平均应力效应已通过Sm​​ith-Watson-Topper和Walker提出的修正得到解决。以此方式，获得了移位因子G的新表达式。通过在其点变体中应用临界距离理论，证明了G对于光滑和缺口几何形状均有效。与汽车工程师协会（SAE）的锁孔测试程序数据进行了比较，以证实结果。
