Prediction of Fatigue Crack Initiation in Complete Contact Fretting Fatigue

Fretting induced cracking is commonly observed in industrial components that are in contact and are subjected to small oscillatory movements between them. Fretting causes a considerable reduction in fatigue strength. In this paper, finite element modeling is used in conjunction with Smith Watson Top...

Zusammenfassung:Fretting induced cracking is commonly observed in industrial components that are in contact and are subjected to small oscillatory movements between them. Fretting causes a considerable reduction in fatigue strength. In this paper, finite element modeling is used in conjunction with Smith Watson Topper (SWT) criterion to estimate crack initiation in fretting. The predictions from the analysis are compared with the experimental results. It is concluded that the analysis must include the effect of residual stress and wear profile with debris effect for better predictions.
