Static friction of automotive friction materials
Wear, 1975The static friction characteristics of filled phenolic resins against gray cast iron were investigated as a function of normal load, P, and temperature, T. A previous study [1, 2] of dynamic friction of filled phenolic resins revealed that these materials do not obey the Amontons law, F = μP, but a power function of the normal load (P) and the sliding ...

Thermal effects in static friction: Thermolubricity
Physical Review E, 2008We present a molecular dynamics analysis of the static friction between two thick slabs. The upper block is formed by N2 molecules and the lower block by Pb atoms. We study the effects of the temperature as well as the effects produced by the structure of the surface of the lower block on the static friction.

Forms of Static Friction, Sliding Friction and Rolling Friction
World Tribology Congress III, Volume 1, 2005Although, it seems that the concepts of static friction, sliding friction and rolling friction are common knowledges, their real sources are ironically not so clear. Inappropriate descriptions of them may have hampered the theoretical analyses and calculations of the frictions and deterred their applications in real world.

Abstract A new machine is described by means of which static friction between contacting surfaces separated by lubricating films of thickness approaching molecular dimensions can be measured with considerable precision. In a test run, a number of spot determinations of the static coefficient are made at closely spaced points over a short

Objectives: Bodies in contact exert a force on each other. In the case of ideally smooth surfaces, this force acts perpendicularly to the contact plane. If the surfaces are rough, however, there may also be a tangential force component. Students will learn that this tangential component is a reaction force if the bodies adhere, and an active force if ...

Driven Colloidal Monolayers: Static and Dynamic Friction
2014Trapping and dragging colloidal monolayers in two-dimensional optical lattices is offering the possibility to mimic friction between crystals (or even quasicrystals) visualizing directly the intimate mechanisms of sliding friction, with the additional possibility to change parameters freely, and to compare directly experiment with theory.

It is shown that the static friction between a soft metal hemisphere and a flat surface increases with the length of time the surfaces have been in contact and that this increase is due to creep. Such creep might account for the difference between static and dynamic coefficients of friction.
