Calculations of the impact of friction and wear on energy consumption, economic
expenditure, and CO 2 emissions are presented on a global scale. This impact study covers …

The prediction of friction under elastohydrodynamic lubrication (EHL) conditions remains
one of the most important and controversial areas of tribology. This is mostly because the …

Engineering Tribology, Fourth Edition is an established introductory reference focusing on
the key concepts and engineering implications of tribology. Taking an interdisciplinary view …

A shear rheological model based on primary laboratory data is proposed for concentrated
contact lubrication. The model is a Maxwell model modified with a limiting shear stress …

The methods of measuring the rheological properties of EHD lubricants are reviewed, but for
pressures in excess of 1.0 GPa there is currently no simple alternative to the disc machine. A …

Measurements of lubricant shear rheological behavior in the amorphous solid region and
near the liquid-solid transition are reported on three lubricants under pressure. Elastic …

Analyses of the dependence of lubricant viscosity on temperature and pressure, μ (T, P),
have been carried out by using a modified WLF equation in which pressure effects on …

The rheological behaviour of the lubricant in an elastohydrodynamic contact depends upon
the properties of the fluid and the imposed conditions of load, speed and temperature. For a …

A limiting shear stress model of liquid lubricant shear rheology is offered which accurately
represents all available primary data. The model is of the nonlinear Maxwell type with shear …

In hard EHL, encountered in, eg, gears, rolling element bearings etc. the properties of the
lubricant play a significant role in the forming of a lubricating film and reducing friction …
