Life Prediction of Fretting Fatigue with Advanced Surface Treatments (Preprint)

Abstract

Laboratory fretting results with diamond like carbon coating, low plasticity burnishing, and laser shock processing as well as with no surface treatments are presented. A method of life prediction for a dovetail type specimen is demonstrated with the laboratory results. In general, the life prediction calculations agree with the laboratory results when the appropriate coefficient of friction and compressive residual stresses are accounted for in the analysis. Some of the assumptions made in the analysis are qualitatively confirmed with experimental observations.
