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…
Advanced Langevin thermostats: Properties, extensions to rheology, and a lean momentum-conserving approach
Shubham Agarwal, Sergey V. Sukhomlinov, Marc Honecker +1
The Langevin equation accounts for unresolved bath degrees of freedom driving the system toward the bath temperature. Because of this, numerical solutions of the Langevin equation…
Cold self-lubrication of sliding ice
Achraf Atila, Sergey V. Sukhomlinov, Martin H. Müser
The low kinetic friction between ice and numerous counterbodies is commonly attributed to an interfacial water layer, which is believed to originate from pre-existing surface water…
Is Ultralow Friction on Graphite Sustainable in Contaminated Environments?
Hongyu Gao, Sergey Sukhomlinov
Structural lubricity arises typically at incommensurate, well-defined dry contacts where short-range elastic instability is significantly mitigated. However, under ambient conditio…
Brittleness of metallic glasses dictated by their state at the fragile-to-strong transition temperature
Achraf Atila, Sergey V. Sukhomlinov, Marc J. Honecker +1
The effect of cooling on the brittleness of glasses in general, and bulk metallic glasses (BMGs) in particular, is usually studied with continuously varying cooling rates; slower c…
