On the flash temperature in sliding rubber contacts
B. N. J. Persson
We present an analytical theory for the flash temperature for viscoelastic solids sliding on rigid and randomly rough surfaces. The theory takes into account the surface roughness…
On the flash temperature in accelerated sliding contacts
B. N. J. Persson
The temperature increase in the contact regions between solids in sliding contact can easily reach several hundred Kelvin and thereby dramatically affect friction and wear. Here I…
Sliding contact creates universal self-affine fractal surfaces
Ruibin Xu, Haohao Ren, Adriane Clerc +4
Surface roughness evolves during sliding, a process known as run-in, and the resulting topography controls friction, leakage, and failure from machines to geological faults. Yet th…
Adhesion-controlled sliding and the Stribeck curve in hydrophobic soft contacts
Ruibin Xu, Charlotte Spies, Michele Scaraggi +1
We present an experimental and theoretical study of dry and glycerol-lubricated sliding for polymethyl methacrylate (PMMA) cylinders with different surface roughness sliding on pol…
On the flash temperature in sliding contacts
M. H. Müser, B. N. J. Persson
The temperature increase in the contact regions between solids in sliding contact can easily reach several hundred Kelvin and thereby dramatically affect friction and wear. The cla…
Granite sliding on granite: friction, wear rates, surface topography, and the scale-dependence of rate-state effects
Sergey V. Sukhomlinov, Martin H. Müser, B. N. J. Persson
We study tribological granite-granite contacts as a model for tectonic faulting, combining experiments, theory, and molecular dynamics simulations. The high friction in this system…
