Numerical Investigation on the Effect of Wear Coefficient on Fretting Wear

Fretting happens when a relative slip occurs between two contact parts. Fretting wear is the main damage in gross slip regime. In most of current researches, the wear coefficient is commonly considered as a constant, which needs further experimental validation. In this paper, bi-linear decreasing wear coefficient numerical model is used to investigate the effect of the variation of wear coefficient on wear profile based on experimental data from literature. It can be concluded that the variation of wear coefficient has a significant effect on the wear profile. Moreover, contact pressure differences are also identified.
