This paper deals with optical experimental methods for improving current knowledge on
particle entrapment in elastohydrodynamic contacts. Particular attention was paid to the …

When the lubricating oil flowing between the contact surfaces contains simulated wear
particles, it is considered that there is a high possibility for the particles to enter between the …

Observing wear debris during friction is crucial for comprehending the wear behavior of
lubrication systems. Despite various techniques attempted for observation, a persistent …

When dealing with joints and bearings, high pressures localised at the contact interface lead
to residual plastic strain. The present paper combines numerical simulations and …

The entrapment/rejection process of spherical, rigid microparticles in elliptical, rough
elastohydrodynamic contacts is modelled. An earlier model of the author is extended to …

Maintenance due to the replacement of damaged wheels and rails due to rolling contact
fatigue (RCF) and wear has been found to be the major problem to rail operating …

The objective of this study is to investigate the effects of the contamination of lubricants on
denting in rolling element bearings. A dynamic, explicit finite element model (FEM) is …

Solid nanoparticles have been applied as anti-wear and friction reduction additives for
lubricants. In this paper, the flow characteristics of solid particles used as additives for …
