A simple deterministic plastoelastohydrodynamic lubrication (PEHL) model in mixed lubrication [PDF]
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]
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

Influence of Cavitation and Shaft Deformation in the Analysis of Lubrication of the Stern Bearing
The cavitation phenomenon and shaft deformation have a significant impact on the tribological performance of the journal bearing. A mixed lubrication model is developed that takes into account surface roughness and asperity contact, as well as the ...
