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 10, where the dimensionless parameter alpha =hrms/delta is the ratio between the root-mean-square roughness amplitude and the penetration for the smooth surfaces case (Hertz contact).
