Using molecular dynamics we study the dependency of the contact mechanics on the sliding speed when an elastic block (cylinder) with a cos(q_{0}x) surface height profile is sliding in adhesive contact on a rigid flat substrate. The atoms on the block interact with the substrate atoms by Lennard-Jones potentials, and we consider both commensurate and (nearly) incommensurate contacts. For the incommensurate system the friction force fluctuates between positive and negative values, with an…

Opposite moving detachment waves mediate stick-slip friction at soft interfaces

Intermittent motion, called stick–slip, is a friction instability that commonly occurs during relative sliding of two elastic solids. In adhesive polymer contacts, where elasticity and interface

On the origin of sliding friction: Role of lattice trapping

Using molecular dynamics we study the dependence of the friction force on the sliding speed when an elastic slab (block) is sliding on a rigid substrate with a ${\rm sin} (q_0 x)$ surface height

Rubber friction on smooth surfaces

A detailed model which takes into account the influence of thermal fluctuations on the depinning of small contact patches at the rubber-substrate interface is developed, predicting that the velocity dependence of the macroscopic shear stress has a bell-shaped form and that the low-velocity side exhibits the same temperature dependence as the bulk viscoelastic modulus.

Evolution of real contact area under shear and the value of static friction of soft materials

The origin of static friction is investigated, the threshold force at which a frictional interface starts to slide, and for rough contacts involving rubber or human skin, the real contact area significantly decreases under increasing shear, well before the onset of sliding.

Attempts to establish the relationship between adhesion and friction at the contact of solid surfaces has been frustrated by their inevitable roughness. The recent development of nanotribology, in

Frictional properties of confined polymers

Molecular dynamics friction calculations for confined hydrocarbon solids with molecular lengths from 20 to 1400 carbon atoms show good correlation with experimental work, indicating an adhesional contribution to the friction force.

Shear-Induced Anisotropy in Rough Elastomer Contact.

It is shown that smooth sphere-plane contacts have the same shear-induced anisotropic behavior as individual microjunctions, with a common scaling law over 4 orders of magnitude in the initial area.

The Interaction of Frictional Slip and Adhesion for a Stiff Sphere on a Compliant Substrate

How friction affects adhesion is addressed. The problem is considered in the context of a very stiff sphere adhering to a compliant, isotropic, linear elastic substrate and experiencing adhesion

Local friction at a sliding interface between an elastomer and a rigid spherical probe

Measurements of the shear stress distribution at a frictional interface between a flat rubber substrate and a glass lens suggest that simple notions of real contact area and constant interface shear Stress cannot account for the observed changes in local friction when roughness is varied.
