Abstract

The properties of asperities are investigated. It is found that the asperity size distribution of asperities can be estimated by the auto-correlation function. New definitions for asperity and asperity curvature are employed. It is found that asperity curvature can be estimated by root mean square curvature of profile. With the finding of this paper: The statistical contact model can be used more accurately.
