Normal contact stiffness of elastic solids with fractal rough surfaces.

Roman Pohrt1, Valentin L Popov.   

Abstract

Using the boundary element method, we calculate the normal interfacial stiffness and constriction resistance of two elastic bodies with randomly rough surfaces and varying fractal dimensions. The contact stiffness as a function of the applied normal force can be approximated by a power law, with an exponent varying from 0.51 to 0.77 for fractal dimensions varying from 2 to 3.
