Contact mechanics-based models for the friction of nominally flat rough surfaces have not
been able to adequately capture certain key experimentally observed phenomena, such as …

Tribochemical reactions can modify the surface structure and chemical properties of
amorphous carbon films during sliding, thereby altering their tribological behavior …

Dry granular materials consist of a vast ensemble of discrete solid particles interacting
through complex frictional forces at the contact points. The particles are so large that these …

Certain polytetrafluoroethylene (PTFE) composites can form a shear localization structure at
the sliding interface by developing running and transfer films, thus achieving an ultralow …

Temperature is one of the governing factors affecting friction of solids. Undesired high
friction state has been generally reported at cryogenic temperatures due to the prohibition of …

Materials age, and their properties can evolve over time scales that in many cases can be
captured in laboratory experiments. Creep is one of the most commonly observed aging …

Frictional aging is observed at a wide range of length-and time-scales, and plays a crucial
role in functioning of micro-and nanomachines, as well as in the nucleation and recurrence …

Surface morphology plays a crucial role in friction between two contacting geomaterial
surfaces, yet many questions remain unanswered regarding how detailed frictional …

This work examines the effect of environmental humidity on rate-and-state friction behavior
of nanoscale silica-silica nanoscale contacts in an atomic force microscope, particularly, its …

This paper investigates why the static friction peak is mostly absent in reciprocating sliding
and gross-slip fretting literature. Here, reciprocating sliding tests were conducted on ultra …
