Properties of the shear stress peak radiated ahead of rapidly accelerating rupture fronts that mediate frictional slip

Jean-François Molinari, Mathilde Edmée Lucette Radiguet de la Bastaie, David Simon Kammer, Daniel Pino Muñoz

We study rapidly accelerating rupture fronts at the onset of frictional motion by performing high-temporal-resolution measurements of both the real contact area and the strain fields surrounding the propagating rupture tip. We observe large-amplitude and l ...

Linear Elastic Fracture Mechanics Predicts the Propagation Distance of Frictional Slip

Jean-François Molinari, Mathilde Edmée Lucette Radiguet de la Bastaie, David Simon Kammer

When a frictional interface is subject to a localized shear load, it is often (experimentally) observed that local slip events propagate until they arrest naturally before reaching the edge of the interface. We develop a theoretical model based on linear e ...

The role of viscoelasticity on heterogeneous stress fields at frictional interfaces

Jean-François Molinari, Mathilde Edmée Lucette Radiguet de la Bastaie, David Simon Kammer

We investigate the evolution of heterogeneous stress states along frictional in- terfaces. Using finite-element simulations, we model the occurrence of precur- sory slip sequences on a deformable-deformable as well as a deformable-rigid interface between t ...

Survival of Heterogeneous Stress Distributions Created by Precursory Slip at Frictional Interfaces

Jean-François Molinari, Philippe Gillet, Mathilde Edmée Lucette Radiguet de la Bastaie, David Simon Kammer

We study the dynamics of successive slip events at a frictional interface with finite-element simulations. Because of the viscous properties of the material, the stress concentrations created by the arrest of precursory slip are not erased by the propagati ...
