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 …

Nonequilibrium molecular dynamics (NEMD) simulations have provided unique insights into
the nanoscale behaviour of lubricants under shear. This review discusses the early history of …

There is currently considerable debate concerning the most appropriate rheological model
to describe the behaviour of lubricant films in rolling–sliding, elastohydrodynamic contacts …

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 …

The EHD friction properties of a wide range of base fluids have been measured and
compared in mixed sliding–rolling conditions at three temperatures and two pressures. The …

A detailed understanding of the behaviour of confined fluids is critical to a range of industrial
applications, for example to control friction in engineering components. In this study, a …

Understanding the molecular-scale behavior of fluids confined and sheared between solid
surfaces is important for many applications, particularly tribology where this often governs …

Although limiting shear stress is a common behavior that is observed in many highly loaded
lubricated contacts, its physical origins are still a matter of debate. Several scenarios are …

The effect of interfacial slip on the friction and film thickness in an elastohydrodynamic (EHD)
contact was directly evaluated. Experiments showed that the film thickness and friction …

A novel methodology, based on the use of phosphorescence imaging, is applied to
determine the local through-thickness velocity profile of lubricant in an elastohydrodynamic …
