Hello,

 

This property defines the fatigue strength reduction factor. This setting enables you to adjust the stress-life or strain-life curve(s) by a specified factor while the fatigue analysis is running. The default value is 1. You set the property by making an entry or you can use the slider feature associated with the property. The slider represents the entry range from minimum (0.01) to maximum (1). You use this property to account for a "real world" environment that may be harsher than a rigidly-controlled laboratory environment in which the data was collected. Common fatigue strength reduction factors to account for such things as surface finish can be found in design handbooks.

 

Here is the link to the  Mechanical User's Guide where you should find all the necessary information regarding Fatigue Analysis Application:
