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).

The measurement of wear using AFM and wear interpretation using a contact mechanics coupled wear model

TL;DR: In this article, the authors used atomic force microscopy (AFM) to measure surface height profiles with high precision, before and after a wear experiment, and calculated the distribution and depth of wear on steel surfaces using a relocation method.

Damage analysis for an elastic-plastic body in cylindrical contact with a rigid plane

TL;DR: In this article, a numerical approach based on the continuum damage mechanics is proposed to conduct the fatigue damage analysis of the material under cyclic loadings, which can be considered as a fundamental simplification of the contact between two rough surfaces.

A Thermal Elastohydrodynamic Lubrication Model for Crowned Rollers and Its Application on Apex Seal–Housing Interfaces

TL;DR: In this paper, a thermal elastohydrodynamic lubrication (EHL) model for analyzing crowned roller lubrication performances under the influence of frictional heating is presented, where the Reynolds equation is solved to obtain the film thickness and pressure results while the energy equation and temperature integration equation are evaluated for the temperature rise in the lubricant and at the surfaces.
