A minimal model for the onset of slip pulses in frictional rupture

Kjetil Thøgersen, Einat Aharonov, Fabian Barras +1

We present a minimal one-dimensional model for the transition from crack-like to pulse-like propagation of frictional rupture. In its non-dimensional form, the model depends on onl…

Finite element modeling of dynamic frictional rupture with rate and state friction

Roozbeh Rezakhani, Fabian Barras, Michael Brun +1

Numerous laboratory experiments have demonstrated the dependence of the friction coefficient on the interfacial slip rate and the contact history, a behavior generically called rat…

The emergence of crack-like behavior of frictional rupture: Edge singularity and energy balance

Fabian Barras, Michael Aldam, Thibault Roch +3

The failure of frictional interfaces -- the process of frictional rupture -- is widely assumed to feature crack-like properties, with far-reaching implications for various discipli…

The emergence of crack-like behavior of frictional rupture: The origin of stress drops

Fabian Barras, Michael Aldam, Thibault Roch +3

The process of frictional rupture, i.e. the failure of frictional systems, abounds in the technological and natural world around us, ranging from squealing car brake pads to earthq…

Unstable slip pulses and earthquake nucleation as a non-equilibrium first-order phase transition

Efim A. Brener, Michael Aldam, Fabian Barras +2

The onset of rapid slip along initially quiescent frictional interfaces, the process of `earthquake nucleation', and dissipative spatiotemporal slippage dynamics play important rol…
