Cylinder-flat contact mechanics with surface roughness

Abstract

We study the nominal (ensemble averaged) contact pressure $p(x)$ acting on a cylinder squeezed in contact with an elastic half-space with random surface roughness. The contact pressure is Hertzian-like for $\alpha <0.01$ and Gaussian-like for $\alpha >10$, where the dimensionless parameter $\alpha =h_{\mathrm{rms}}/\delta$ is the ratio between the root-mean-square roughness amplitude and the penetration for the smooth surfaces case (Hertz contact).
