Breakdown of the classical rupture theory and earthquake propagation in the "forbidden" super-Rayleigh range
Anna Pomyalov, Fabian Barras, Eran Bouchbinder
Earthquakes propagating faster than the shear wave-speed are commonly thought to undergo a super-shear transition upon which they discontinuously jump from the sub-Rayleigh regime…
Unveiling the role of seepage forces in the acceleration of landslides creep
Fabian Barras, Andreas Aspaas, Einat Aharonov +1
In the context of global climate change, geological materials are increasingly destabilized by water flow and infiltration. We study the creeping dynamics of a densely monitored la…
Thermo-viscous instability of flow in a weakly heat-conducting channel
Federico Lanza, Gaute Linga, Fabian Barras +1
An instability may arise when a hot viscous fluid enters a thin gap and cools through heat transfer to a colder surrounding environment. Fluids whose viscosity increases strongly u…
Shear localisation controls the dynamics of earthquakes
Fabian Barras, Nicolas Brantut
Earthquakes are produced by the propagation of rapid slip along tectonic faults. The propagation dynamics is governed by a balance between elastic stored energy in the surrounding…
The dynamics of unsteady frictional slip pulses
Anna Pomyalov, Fabian Barras, Thibault Roch +2
Self-healing slip pulses are major spatiotemporal failure modes of frictional systems, featuring a characteristic size and a propagation velocity ( is time…
On the scale dependence in the dynamics of frictional rupture: constant fracture energy versus size-dependent breakdown work
Federica Paglialunga, François Passelègue, Nicolas Brantut +3
Potential energy stored during the inter-seismic period by tectonic loading around faults is released during earthquakes as radiated energy, heat and fracture energy. The latter is…
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…
Onset of sliding across scales: How the contact topography impacts frictional strength
Fabian Barras, Ramin Aghababaei, Jean-François Molinari
When two solids start rubbing together, frictional sliding initiates in the wake of slip fronts propagating along their surfaces in contact. This macroscopic rupture dynamics can b…
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…
