Diffusion-driven frictional aging in silicon carbide
Even Marius Nordhagen, Henrik Andersen Sveinsson, Anders Malthe-Sørenssen
Friction is the force resisting relative motion of objects. The force depends on material properties, loading conditions and external factors such as temperature and humidity, but…
Using Computational Essays to Redistribute Epistemic Agency in Undergraduate Science
Tor Ole B. Odden, Devin Silvia, Anders Malthe-Sørenssen
This article reports on a study investigating how computational essays can be used to redistribute epistemic agency--cognitive control and responsibility over one's own learning--t…
Using Computational Essays to Scaffold Professional Physics Practice
Tor Ole Odden, Anders Malthe-Sørenssen
This article describes a curricular innovation designed to help students experience authentic physics inquiry with an emphasis on computational modeling and scientific communicatio…
A minimal model for slow, sub-Rayleigh, super-shear and unsteady rupture propagation along homogeneously loaded frictional interfaces
Kjetil Thøgersen, Henrik Andersen Sveinsson, David Skålid Amundsen +3
In nature and experiments, a large variety of rupture speeds and front modes along frictional interfaces are observed. Here, we introduce a minimal model for the rupture of homogen…
Statistics of the separation between sliding rigid rough surfaces: Simulations and extreme value theory approach
Nicolas Ponthus, Julien Scheibert, Kjetil Thøgersen +2
When a rigid rough solid slides on a rigid rough surface, it experiences a random motion in the direction normal to the average contact plane. Here, through simulations of the sepa…
Steady-state propagation speed of rupture fronts along one-dimensional frictional interfaces
David Skålid Amundsen, Jørgen Kjoshagen Trømborg, Kjetil Thøgersen +3
The rupture of dry frictional interfaces occurs through the propagation of fronts breaking the contacts at the interface. Recent experiments have shown that the velocities of these…
On the speed of fast and slow rupture fronts along frictional interfaces
Jørgen Kjoshagen Trømborg, Henrik Andersen Sveinsson, Kjetil Thøgersen +2
The transition from stick to slip at a dry frictional interface occurs through the breaking of the junctions between the two contacting surfaces. Typically, interactions between th…
Intermolecular Casimir-Polder Forces in Water and near Surfaces
Priyadarshini Thiyam, Clas Persson, Bo E. Sernelius +3
The Casimir-Polder force is an important long range interaction involved in adsorption and desorption of molecules in fluids. We explore Casimir-Polder interactions between methane…
History-dependent friction and slow slip from time-dependent microscopic junction laws studied in a statistical framework
Kjetil Thøgersen, Jørgen Kjoshagen Trømborg, Julien Scheibert +2
To study the microscopic origins of friction, we build a framework to describe the collective behaviour of a large number of individual micro-junctions forming a macroscopic fricti…
Slow slip and the transition from fast to slow fronts in the rupture of frictional interfaces
Jørgen Kjoshagen Trømborg, Henrik Andersen Sveinsson, Julien Scheibert +3
The failure of the population of micro-junctions forming the frictional interface between two solids is central to fields ranging from biomechanics to seismology. This failure is m…
A 4D synchrotron X-ray tomography study of the formation of hydrocarbon migration pathways in heated organic-rich shale
Hamed Panahi, Maya Kobchenko, Francois Renard +6
Recovery of oil from oil shales and the natural primary migration of hydrocarbons are closely related processes that have received renewed interests in recent years because of the…
Transition from static to kinetic friction: Insights from a 2D model
Jørgen Trømborg, Julien Scheibert, David Skålid Amundsen +2
We describe a 2D spring-block model for the transition from static to kinetic friction at an elastic slider/rigid substrate interface obeying a minimalistic friction law (Amontons-…
4D imaging of fracturing in organic-rich shales during heating
Maya Kobchenko, Hamed Panahi, Francois Renard +6
To better understand the mechanisms of fracture pattern development and fluid escape in low permeability rocks, we performed time-resolved in situ X-ray tomography imaging to inves…
