<p>On the basis of experimental results, in this paper is proposed a new friction law aiming atdescribing the mechanical behavior of thick gouge layers. In the present paper, the objective is to derive an empirical friction law capable of accounting for this ...

Accelerating displacements preceding some catastrophic landslides have been found to display a finite time singularity of the velocity v. Here we provide a physical basis for this phenomenological law based on a slider block model using a state- and velocity-dependent ...
