Friction will cease publication with Springer Nature on completion of Volume 12/2024. The journal will continue in cooperation with Tsinghua University Press from Volume 13/2025.

May 5, 2025 · We discuss different forms of friction, static friction, kinetic friction, and rolling friction, and show how the resulting frictional forces can be parameterized.

Jul 4, 2023 · The measurement method of internal friction can be selected according to the frequency range, sample size, and internal friction. There are five commonly used methods.

Two types of friction coefficient are distinguished: the static friction coefficient and the kinetic friction coefficient. The former is sometimes called the starting friction coefficient, and the latter …

A few common friction measurement methods are described here, and the reader is referred both to the bibliography and to other application-specific articles in this encyclopedia for additional …

Friction and wear are system responses, rather than material properties. The measurement of tribological behavior therefore poses particular challenges, and a keen awareness of the …

Mar 7, 2017 · The shape of the coarse sand grains creates an equivalent roughness in the sample and is responsible for much of the nonlinear character in its shear strength. The angle of …

Friction plays important and multiple roles in the operation of dynamic seals. Since friction dissipates energy, it can reduce the efficiency of a mechanical/electrical system.

Dating back to 1699, Amontons’ laws of friction assert that there exists a proportionality between friction force and the applied load, and that the friction force is independent of apparent …
