Description of the transitional process from a static to a dynamic frictional\nregime is a fundamental problem of modern physics. Previously, we developed a model\nbased on the well-known Frenkel-Kontorova model to describe dry macroscopic friction.\nHere, this model has been modified to include the effect of dissipation in derived relations\nbetween the kinematic and dynamic parameters of a transition process. The main\n(somewhat counterintuitive) result is a demonstration that the rupture (i.e., detachment\nfront) velocity of the slip pulse which arises during the transition does not depend on\nfriction. The only parameter (besides the elastic and plastic properties of the medium)\ncontrolling the rupture velocity is the shear to normal stress ratio. In contrast to the rupture\nvelocity, the slip velocity does depend on friction. The model we have developed describes\nthese processes over a wide range of rupture and slip velocities (up to 7 orders of\nmagnitude) allowing, in particular, the consideration of seismic events ranging from\nregular earthquakes, with rupture velocities on the order of a few km/s, to slow slip events,\nwith rupture velocities of a few km/day.
