We introduce a model of friction between two contacting (stationary or co-sliding) rough surfaces, each comprising a random ensemble of polydisperse hemispherical bumps. In the simplest version of the model, the bumps experience on contact with each other only pairwise elastic repulsion and dissipative drag. These minimal ingredients are sufficient to capture a static state of jammed, interlocking contacting bumps, below a critical frictional force that is proportional to the normal load and…

Solid friction from stick–slip down to pinning and aging

We review the present state of understanding of solid friction at low velocities and for systems with negligibly small wear effects. We first analyze in detail the behavior of friction at interfaces

Modeling of rock friction: 1. Experimental results and constitutive equations

Direct shear experiments on ground surfaces of a granodiorite from Raymond, California, at normal stresses of ∼6 MPa demonstrate that competing time, displacement, and velocity effects control rock

How collective asperity detachments nucleate slip at frictional interfaces

TLDR
A microscopic model of a frictional interface that includes asperity-level disorder, elastic interaction between local slip events, and inertia is introduced, and it is found that after slip, the density of asperities at a local distance to yielding xσ presents a pseudogap P(xσ)∼( xσ)θ, where θ is a nonuniversal exponent that depends on the statistics of the disorder.

Finite-size scaling in the interfacial stiffness of rough elastic contacts.

The total elastic stiffness of two contacting bodies with a microscopically rough interface has an interfacial contribution K that is entirely attributable to surface roughness. A quantitative

Molecular probes reveal deviations from Amontons’ law in multi-asperity frictional contacts

TLDR
A new contact detection method is presented to show that the law of Amontons’ law is broken because asperities interact and deform in the contact area to change it, thereby also changing the friction force.

Rheological aging and rejuvenation in solid friction contacts

TLDR
It is shown that low-velocity frictional properties of interfaces between a rough glassy polymer and smooth silanized glass exhibit the full phenomenology expected for confined quasi-2D soft glasses: they strengthen logarithmically when aging at rest, and weaken when sliding.

TLDR
A scaling analysis for the load balance in sliding friction in the hydrodynamic lubrication regime suggests that normal stress and flow transience do not destroy this basic picture, although they may provide stabilising mechanisms at higher shear rates.

The Dynamics of the Onset of Frictional Slip

TLDR
The ratio of shear stress to normal stress can locally far exceed the static-friction coefficient without precipitating slip and different modes of rupture selected by the system correspond to distinct regimes of the local stress ratio.

Dynamics of transition from static to kinetic friction.

TLDR
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.

Brittle Fracture Theory Describes the Onset of Frictional Motion

Contacting bodies subjected to sufficiently large applied shear will undergo frictional sliding. The onset of this motion is mediated by dynamically propagating fronts, akin to earthquakes, that
