When two bodies are in contact, various surface/subsurface damage problems may arise,
which significantly shorten the service lives of functional components. These damage …

This review summarizes recent advances in the area of tribology based on the outcome of a
Lorentz Center workshop surveying various physical, chemical and mechanical phenomena …

Many devices, including touchscreens and robotic hands, involve frictional contacts.
Optimizing these devices requires fine control of the interface's friction law. We lack …

In typical metallic contacts, stresses are very high and result in yielding of the material.
Therefore, the study of contacts which include simultaneous elastic and plastic deformation …

Recent direct implementation of asperity theories is reinterpreted here to formulate an
improved version of the Greenwood and Williamson (GW) theory with the inclusion of …

The size of the mechanical contact between nanoscale bodies that are pressed together
under load has implications for adhesion, friction, and electrical and thermal transport at …

In this work, we discuss important improvements of asperity models. Specifically, we assess
the predictive capabilities of a recently developed multiasperity model, which differs from the …

It is commonly assumed that knowing the height auto-correlation function of two solids in
contact along with their materials properties is sufficient to predict the contact pressure …

The optimization of surface finish to improve performance, such as adhesion, friction, wear,
fatigue life, or interfacial transport, occurs largely through trial and error, despite significant …

Tribological phenomena are governed by combined effects of material properties, topology
and surface-chemistry. We study the interplay of multiscale surface structures with molecular …
