A simple deterministic plastoelastohydrodynamic lubrication (PEHL) model in mixed lubrication [PDF]
Tribology International, 2019 Most power transmitting components operate under mixed lubrication conditions. Concentrated pressures and smaller lubricant film thickness may cause surface and subsurface stresses to exceed the material yield limit causing permanent geometrical changes.

A Review of Mixed Lubrication Modelling and Simulation [PDF]
Tribology in Industry, 2022 Most rolling contacts found in machine elements such as gears and bearings operate under Mixed Lubricating (ML) conditions, where the lubricant film can’t fully separate the asperities of the two contacting surfaces. Highly loaded, interacting asperity surrounded with lubricant film, leads to the development of surface originated defects such as ...
