On the Use of the areaΔ and the Three-Parameter Model to Estimate High Cycle Fatigue Life
In our previous work, a parameter a, r, e, a, , Δ, , , , , , , , was proposed to describe fatigue damage caused by micro scratch, whose validity was verified by fracture mechanics. In this article, we summarize an attempt to check the applicability of the a, r, e, a, , Δ, , , , , , , , in the field of the classic S-N curve method. For the sake of objective verification, the experiment data used in this article are from our published work. A high cycle fatigue life model of TC17 based on micro scratches is established with the synthesis of the three-parameter model and Murakami equation modified by a, r, e, a, , Δ, , , , , , , , . Prediction results gave accuracy to mainly fall into the scatter band of factor 2. It can be suggested that a, r, e, a, , Δ, , , , , , , , is suitable for being used in both fracture mechanics and classic S-N curve method. Furthermore, the validity of a, r, e, a, , Δ, , , , , , , , in fatigue behavior analysis combined with current fatigue theories and materials is summarized. The measurement method of scratch depth and width suitable for a, r, e, a, , Δ, , , , , , , , is also introduced.
