Stochastic Properties of Static Friction [PDF]

, 2020
The onset of frictional motion is mediated by rupture-like slip fronts, which nucleate locally and propagate eventually along the entire interface causing global sliding.

Optimization calculation method and weighing test of static friction coefficient of RPC spherical joint based on half space contact model

IOP Conference Series: Earth and Environment, 2020
The application of new concrete materials in bridge engineering has always been a research direction of bridge scholars. Reactive powder concrete (RPC) has attracted many scholars’ attention in recent years due to its high strength, high toughness and ...

Friction anisotropy at Ni(100)/(100) interfaces: Molecular dynamics studies [PDF]

, 2002
The friction of surfaces moving relative to each other must derive from the atomic interaction at interfaces. However, recent experiments bring into question the fundamental understanding of this phenomenon.

Geometry of Frictionless and Frictional Sphere Packings [PDF]

, 2001
We study static packings of frictionless and frictional spheres in three dimensions, obtained via molecular dynamics simulations, in which we vary particle hardness, friction coefficient, and coefficient of restitution.

Measurement Method of Static Friction by a Piezoelectric Impact Drive Mechanism

Tribology Online, 2008
The coefficient of static friction is one of the basic factors of actuator performance; it influences the operational characteristics of actuators. In this present study we focus on the dependence of the coefficient of static friction on the time of ...

Static and sliding contact of rough surfaces: effect of asperity-scale properties and long-range elastic interactions [PDF]

, 2018
Friction in static and sliding contact of rough surfaces is important in numerous physical phenomena. We seek to understand macroscopically observed static and sliding contact behavior as the collective response of a large number of microscopic ...
