    Friction'
  title_type: original
  lang: en

## Description

- description: The Amontons-Coulomb friction law assumes that the frictional force
    between materials is independent of sliding velocity. However, as Coulomb noted,
    this is a rough approximation, and a second-order dependence of friction on the
    logarithm of sliding velocity is incorporated in a commonly used ‘rate- and state-dependent’
    friction representation. Here we conduct shear experiments on mica, a layer-structured
    mineral, at temperatures ranging from 22 to 200 ºC and under normal stress of
    100 MPa. The friction coefficient clearly depends on the logarithmic sliding velocity
    at 22 ºC, but rate sensitivity decreases with increasing temperature until at
    200 ºC, the friction coefficient is independent of sliding velocity. Our findings
    could initiate the development of velocity-independent frictional materials, realizing
    the ideal Amontons-Coulomb friction.
