Mixed elastohydrodynamic lubrication analysis of line contact with Non-Gaussian surface roughness

An approach for mixed elastohydrodynamic lubrication (EHL) analysis of line contact with non-Gaussian rough surface is proposed, and a minimum film thickness formula is derived based on the simultaneous solutions. The Patir and Cheng's average flow model and Kogut and Etsion's rough surfac...
