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…
Crack Nucleation in the Adhesive Wear of an Elastic-Plastic Half-Space
Lucas Frérot, Guillaume Anciaux, Jean-François Molinari
The detachment of material in an adhesive wear process is driven by a fracture mechanism which is controlled by a critical length-scale. Previous efforts in multi-asperity wear mod…
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…
Adhesive wear and interaction of tangentially loaded micro-contacts
Son Pham-Ba, Tobias Brink, Jean-François Molinari
Current engineering wear models are often based on empirical parameters rather than built upon physical considerations. Here, we look for a physical description of adhesive wear at…
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…
