Experimental investigation of the frictional behavior of single glass fiber filament

Journal of Engineered Fibers and Fabrics, 2023
Fiber friction behaviors are crucial for understanding the ubiquitous frictional damage phenomena in the manufacturing and service processes of multiscale textile reinforcements. This paper investigates the influence of relative velocity and applied load

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.

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.

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.
