On the nature of the static friction, kinetic friction and creep
Wear, 2003 Abstract In this paper, we discuss the nature of the static and kinetic friction, and of (thermally activated) creep. We focus on boundary lubrication at high confining pressure (∼1 GPa), as is typical for hard solids, where one or at most two layers of confined molecules separates the sliding surfaces.

Abstract An apparatus based on a pendulum hanging around a revolving drum of ice was developed to measure the kinetic friction between a slider and an ice surface under conditions commonly experienced in ice skating (temperatures from -15 to -1°C and velocities from 0.2 to 10m s-1).

THE ordinary static friction apparatus with one mass m hanging over a pulley and connected to another mass M resting on the friction board may be used to determine the kinetic coefficient. Let m be more than sufficient just to move M, and let h be the vertical height over which m is allowed to accelerate M; then, if x is the extra distance along the ...

FROM the recent paper by Morgan, Muskat and Reed1, on “Friction Phenomena and the Stick-Slip Process”, it is apparent that their ideas and experiments are progressing on lines similar to our own.

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 ...

A study of static and kinetic friction
International Journal of Engineering Science, 1990It is the objective of this work to present and discuss various numerical studies on low speed frictional sliding phenomena which strongly suggest that classical interpretations for these phenomena should be critically re-examined and the role played by the dynamic properties of the experimental apparati should be carefully taken into account.

The coefficient of kinetic friction for aluminum
Wear, 1986Abstract The translational and rotational motions of a cylinder traveling down a straight incline, which provides a constant linear acceleration, depend on the angle of inclination. For small angles above the horizontal, free rolling takes place, but, above a critical angle, rolling and slipping occur.

Tribochemical kinetics of external friction
Russian Engineering Research, 2017The kinetics of external friction is compared with the molecular–mechanical theory of friction. It is shown that research on the topochemical kinetics of adhesive binding is still in its early stages. Calculation methods that incorporate experimental data must be developed.
