Abstract
Rate- and state-dependent friction law for velocity-step tests is analyzed from a thermodynamic point of view. A simple macroscopic non- equilibrium thermodynamic model with a single internal variable reproduces instantaneous jump and relaxation. Velocity weakening appears as a conse- quence of a plasticity related nonlinear coefficient. Permanent part of dis- placement corresponds to plastic strain, and relaxation effects are analogous to creep in thermodynamic rheology.
