Macroscopic sliding between two solids is triggered by the propagation of a micro-slip front along the frictional interface. In certain conditions, sliding is preceded by the propagation of aborted fronts, spanning only part of the contact interface. The selection of the characteristic size spanned by those so-called precursors remains poorly understood. Here, we introduce a 1D toy model of precursors between a slider and a track in which the fronts are quasi-static self-healing slip pulses…

2D numerical model for studying frictional sliding
The onset of frictional motion couples complex spatiotemporal dynamics of discrete contacts with different orders of magnitude at time and length scales. In order to reveal how these individual
Speed of fast and slow rupture fronts along frictional interfaces.
Simulations in an elastic two-dimensional spring-block model where the frictional interaction between each interfacial block and the substrate arises from a set of junctions modeled explicitly find that material slip speed and rupture front speed are proportional across the full range of front speeds.
Onset of Sliding of Elastomer Multicontacts: Failure of a Model of Independent Asperities to Match Experiments
Modeling of rough frictional interfaces is often based on asperity models, in which the behavior of individual microjunctions is assumed. In the absence of local measurements at the microjunction
Minimal model for slow, sub-Rayleigh, supershear, and unsteady rupture propagation along homogeneously loaded frictional interfaces.
A minimal model for the rupture of homogeneously loaded interfaces with velocity strengthening dynamic friction is introduced, containing only two dimensionless parameters; τ[over ¯], which governs the prestress, and α[over¯], which is set by the interfacial viscosity.
Microscopic Evolution of Laboratory Volcanic Hybrid Earthquakes
By studying acoustic phonon emissions from individual microcracking events, it is shown that the onset of a secondary instability–related to the transition from HF to LF–occurs during the fast equilibration phase of the system, leading to sudden increase of fluid pressure in the process zone.

Nucleation and Propagation of Quasi-Static Interfacial Slip Pulses
We report thorough experimental characterization of the nucleation and stationary propagation of self-healing slip pulses at a gel/glass interface under constant stress loading. We show that the slip
Self-healing slip pulses and the friction of gelatin gels
The observed ageing of the static friction threshold reveals the slow increase of adhesive bonding between chain ends and glass, compatible with the existence of a velocity-weakening regime at velocities smaller than Vc, hence with theexistence of the healing instability.
Probing the micromechanics of a multi-contact interface at the onset of frictional sliding
Digital Image Correlation is used to study the micromechanics of a multi-contact interface formed between a rough elastomer and a smooth glass surface. The in-plane elastomer deformation is monitored
Detachment fronts and the onset of dynamic friction
It is shown that the onset of frictional slip is governed by three different types of coherent crack-like fronts: these are observed by real-time visualization of the net contact area that forms the interface separating two blocks of like material.
Dynamics of transition from static to kinetic friction.
It is found that the onset of sliding is preceded by well-defined detachment fronts initiated at the slider trailing edge and extended across the slider over limited lengths smaller than the overall length of the slider.
Transition from static to kinetic friction: insights from a 2D model.
A 2D spring-block model for the transition from static to kinetic friction at an elastic-slider-rigid-substrate interface obeying a minimalistic friction law (Amontons-Coulomb) is described and a prediction for the evolution of the precursor length as a function of the applied loads is derived.
Dynamics of precursors to frictional sliding.
The spatial and temporal behavior of the true contact area A along a rough spatially extended interface between two blocks in frictional contact is measured to show that when frictional sliding occurs, the initially uniform contact area along the interface has already evolved to one that is highly nonuniform in space.
Hysteresis and elastic interactions of microasperities in dry friction
Abstract:Velocity independent dry friction of a slider upon a base is due to an hysteretic response of relative displacement ρ to a tangential driving force F. We show that the purely elastic model
Precursors of Global Slip in a Longitudinal Line Contact Under Non-Uniform Normal Loading
This article describes the mechanism of precursor events; the mechanism was determined through an experiment and simulation by considering non-uniform normal loading. In the experiment, real-time
Probing locally the onset of slippage at a model multicontact interface.
The multicontact frictional dynamics of model elastomer surfaces rubbed against bare glass slides are reported on and a simple quasistatic model relying on the existence of interfacial stress gradients is derived and predicts qualitatively the position of slip precursors.
