Effect of track roughness generated micro-hysteresis on rubber friction in case of (apparently) smooth surfaces

In this study, the work of Mofidi et al., 2008 [6] is cited and the focus is put on the finding that the friction reported for lubricated apparently smooth surfaces (sealing applications) may be dominated by micro- or surface roughness generated hysteresis. Contrary to the very high coefficients of friction measured, Mofidi et al. did not analyze their test results and test configuration in depth and did not compare their results to experimental observations taken from the literature. In this study, the author makes an attempt to meet these needs and reanalyze/reinterpret the results of Mofidi et al.
