Onset of sliding across scales: How the contact topography impacts frictional strength

Jean-François Molinari, Ramin Aghababaei, Fabian Barras

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 be successfully mapped on the elastodynamics of a moving shear crack. However ...
