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.

Modelling tribochemistry in the mixed lubrication regime [PDF]
Tribology International, 2019 Mixed lubrication is a contact condition when the total load is carried by both the fluid lubricant and the solid contacting asperities. The aim of this study is to couple tribochemistry with lubrication. A recent semi-deterministic tribochemical model of tribofilm growth is integrated in a deterministic mixed lubrication model. The model considers the

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 ...

Lubricants, 2022 Low-loss gears are an interesting design approach for increasing the efficiency and thermal load limits of gearboxes. The loss-optimized gear geometry concentrates sliding around the pitch point, which results in low load-dependent gear power losses.
