Abstract
Numerical techniques to characterize the asperities of the micro-topography have
been developed and applied for analysing the contact conditions and the wear
progress of polymer composites sliding over steel surfaces.
To identify the asperities one by one, an asperity identification technique has
been developed. The characteristic features of the asperities are approximated by
introducing hemispherical, ellipsoidal, parabolic, conical and pyramid surfaces
as substituting surfaces.
The asperity substitution and statistical analysis allow also conclusions about
the wear progress of surfaces in sliding contact, based on statistical comparison
of the original and worn surfaces.
1. Introduction
The phenomenon of sliding contact has been studied for many centuries. With
the development of diffe
