Energy dissipation at the atomic scale explains how fracture energy depends on crack velocity in silica glass
Marthe Grønlie Guren, Sigbjørn Løland Bore, François Renard +1
The fracture energy of brittle materials rises with crack velocity, and this effect is typically attributed to surface roughening from path instabilities. Here we show, using molec…
Why ice is so slippery
Sigbjørn Løland Bore, B. N. J. Persson, Henrik Andersen Sveinsson
We simulate nanoscale ice--glass friction from first principles and upscale it by modelling frictional heating. Nanoscale simulations alone overestimate friction and miss its veloc…
Neural Networks for Predicting Permeability Tensors of 2D Porous Media: Comparison of Convolution- and Transformer-based Architectures
Sigurd Vargdal, Paula Reis, Henrik Andersen Sveinsson +1
Permeability is a central concept in the macroscopic description of flow through porous media, with applications spanning from oil recovery to hydrology. Traditional methods for de…
Learning atomic forces from uncertainty-calibrated adversarial attacks
Henrique Musseli Cezar, Tilmann Bodenstein, Henrik Andersen Sveinsson +3
Adversarial approaches, which intentionally challenge machine learning models by generating difficult examples, are increasingly being adopted to improve machine learning interatom…
Tailoring Frictional Properties of Surfaces Using Diffusion Models
Even Marius Nordhagen, Henrik Andersen Sveinsson, Anders Malthe-Sørenssen
This Letter introduces an approach for precisely designing surface friction properties using a conditional generative machine learning model, specifically a diffusion denoising pro…
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…
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…
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…
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…
