Contact mechanics: relation between interfacial separation and load

Soft Condensed Matter 2007-10-01 v1

Abstract

I study the contact between a rigid solid with a randomly rough surface and an elastic block with a flat surface. I derive a relation between the (average) interfacial separation uu and the applied normal squeezing pressure pp. I show that for non-adhesive inte raction and small applied pressure, p is proportional to exp (-u/u_0), in good agreement with recent experimental observation.
