Mixed elastohydrodynamic lubrication model for finite roller-coated half space interfaces
TL;DR: In this article, a mixed elastohydrodynamic lubrication (EHL) model for finite roller-coated half space interfaces is presented, which is built with the unified mixed lubrication approach and the influence coefficients relating the pressure on a contact surface to surface deformations and subsurface stresses, converted from the frequency response functions (FRFs).
