Random close packing fraction of bidisperse discs: theoretical derivation
Raphael Blumenfeld
Predicting theoretically the highest density, which a disordered packing of discs can achieve, has been a long-standing unresolved problem. Such predictions are hindered by two dif…
Effects of particle angularity on granular self-organization
Dominik Krengel, Haoran Jiang, Takashi Matsushima +1
Recent studies of two-dimensional poly-disperse disc systems revealed a coordinated self-organisation of cell stresses and shapes, with certain distributions collapsing onto a mast…
Self-organization, detailed balance, and stress-structure correlations in 2D granular dynamics
Raphael Blumenfeld, Takashi Matsushima, Jie Zhang
We argue that a number of recent experimental and numerical observations point to an ongoing cooperative stress-structure self-organisation (SO) in quasi-static granular dynamics.…
Force chains bias the dynamic response to impacts in rubble-pile asteroids
Chenyang Huang, Yang Yu, Peter R. King +2
The impact response of rubble-pile asteroids is essential for both elucidating their formation and evolution history and evaluating the efficacy of impact defense strategies. Altho…
Detailed balance in non-equilibrium dynamics of granular matter: derivation and implications
Clara C. Wanjura, Amelie Mayländer, Othmar Marti +1
Modelling the dynamics of dense granular media is a long standing challenge and essential to many natural phenomena and technological applications. Here, we trace back puzzling exp…
