The Decrease of Static Friction Coefficient with Interface Growth from Single to Multiasperity Contact
Liang Peng, Thibault Roch, Daniel Bonn +1
The key parameter for describing frictional strength at the onset of sliding is the static friction coefficient. Yet, how the static friction coefficient emerges at the macroscale…
Stick-slip phenomena and Schallamach waves captured using reversible cohesive elements
Evelyne Ringoot, Thibault Roch, Jean-François Molinari +2
Reversibility is of paramount importance in the correct representation of surface peeling in various physical settings, ranging from motility in nature, to gripping devices in robo…
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…
