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…
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…
On the viscous dissipation caused by randomly rough indenters in smooth sliding motion
Sergey Sukhomlinov, Martin H. Müser
The viscous dissipation between rigid, randomly rough indenters and linearly elastic counter bodies sliding past them is investigated using Green's function molecular dynamics. The…
