IJTC2011-61013 LUBRICATION OF 2D SOFT ELASTO HYDRODYNAMIC CONTACTS: EXTENSION OF THE AMPLITUDE REDUCTION THEORY
ABSTRACT This paper is an extension of the Amplitude Reduction Theory to soft ElastoHydrodynamic contacts. The ART permits a quantitative prediction of the influence of surface roughness on the lubricant film thickness modification as a function of the operating conditions
Interfacial separation between elastic solids with randomly rough surfaces: comparison between theory and numerical techniques
We study the distribution of interfacial separations P(u) at the contact
region between two elastic solids with randomly rough surfaces. An analytical
expression is derived for P(u) using Persson's theory of contact mechanics, and
is compared to numerical solutions obtained using (a) a half-space method based
on the Boussinesq equation, (b) a Green's function molecular dynamics technique
and (c) smart-block classical molecular dynamics. Overall, we find good
agreement between all the different approaches.Comment: 25 pages, 12 figure
