The Neuber’s Rule and a Correlation Between Fretting Fatigue and Plain Fatigue

Abstract

Based on these experimental observations and on the remark that any small change on the discontinuity geometry has a significant effect on the stress distribution around it, a stress concentration factor is mandatory to be incorporated into the fatigue models in order to accurately predict the life. In this paper, it is proposed a correlation between the global degradation processes in plain fatigue case and the local degradation process in fretting fatigue case.
