TL;DR
This paper develops a thermodynamic framework to unify classical models of rock friction, analyzing rate- and state-dependent laws for velocity changes and healing processes.
Contribution
It introduces a thermodynamic approach that unifies Dieterich and Ruina friction models based on logarithmic deviations from steady-state.

Thermodynamic interpretation of velocity-step behavior
Insights into healing processes in friction
Abstract
Rate- and state-dependent friction law for velocity-step and healing are analysed from a thermodynamic point of view. Assuming a logarithmic deviation from steady-state a unification of the classical Dieterich and Ruina models of rock friction is proposed.
