[SCG59-04] Non-equilibrium thermodynamical interpretation for rate- and state-dependent friction law
Keywords:friction, constitutive law, non-equilibrium thermodynamics, evolution law
Several versions of evolution law have been proposed in order to reproduce the experimental data better. However, none of them are completely satisfied.
We analyze this rate- and state-dependent friction law for the velocity-step and the healing tests from a thermodynamic point of view. Assuming a logarithmic deviation from steady-state, both results are reproduced. The proposed system of equations is a unification of the classical models (Dieterich, 1979; Ruina, 1983).
