Adhesive contact modelling based on lennardjones force law
Lee, W.G1, Chong, W.W.F2.
At diminishing separations, the load carrying capacity of opposing rough surfaces is
distributed among asperities across a smaller contact area as compared with the
apparent contact area. An improved understanding on asperity interactions is
therefore required in order to better predict the tribological behaviour of a rough
surface contact. In this paper, based on Weir’s method for computing the work of
adhesion, a simplistic adhesive contact model is proposed, applying the Lennard-Jones
force law, to study an asperity pair interaction. Assuming that the tip represents an
asperity, the numerical model is subsequently applied to simulate a Tungsten Carbide
(WC) coated AFM tip indenting on a Diamond (111) surface. It was found that the
simulated pull-off force agrees with the measured value by Enachescu et al for a WC
AFM tip on a Diamond (111).
