Non-Equilibrium Thermodynamical Framework for Rate- and State-Dependent Friction
Rateand state-dependent friction laws 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.
متن کاملRate and State Dependent Friction and the Stability of Sliding Between Elastically Deformable Solids
We study the stability of steady sliding between elastically deformable continua using rate and state dependent friction laws. That is done for both elastically identical and elastically dissimilar solids. The focus is on linearized response to perturbations of steady state sliding, and on studying how the positive direct effect (instantaneous increase or decrease of shear strength in response ...
متن کاملRate- and state-dependent friction law and statistical properties of earthquakes
– In order to clarify how the statistical properties of earthquakes depend on the constitutive law characterizing the stick-slip dynamics, we make an extensive numerical simulation of the one-dimensional spring-block model with a rateand state-dependent friction law. Both the magnitude distribution and the recurrence-time distribution are studied with varying the constitutive parameters charact...
متن کاملSelf-similar slip instability on interfaces with rate- and state-dependent friction.
We examine the development of a frictional instability, with diverging sliding rate, at the interface of elastic bodies in contact. Evolution of friction is determined by a slip rate and state dependence. Following Viesca (2016 Phys. Rev. E93, 060202(R). (doi:10.1103/PhysRevE.93.060202)), we show through an appropriate change of variable, the existence of blow-up solutions that are fixed points...
متن کاملAfterslip and aftershocks in the rate-and-state friction law
We study how a stress perturbation generated by a mainshock affects a population of faults obeying a rate-state friction law. Depending on the model parameters and on the initial state, the fault exhibits aftershocks, slow earthquakes, or decaying afterslip. We found several regimes with slip rate decaying as a power-law of time, with different characteristic times and exponents. The complexity...
