Self-organisation in hard-soft granular mixtures
Haoran Jiang, Dominik Krengel, Takashi Matsushima +1
Self-organisation of granular systems is a key determinant of their macroscopic behaviour and has been studied extensively in assemblies of hard particles. We use numerical simulat…
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…
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.…
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…
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…
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…
Comment on "Explicit Analytical Solution for Random Close Packing in d=2 and d=3", Physical Review Letters {\bf 128}, 028002 (2022)
Raphael Blumenfeld
The method, proposed in \cite{Za22} to derive the densest packing fraction of random disc and sphere packings, is shown to yield in two dimensions too high a value that (i) violate…
Fundamental structural characteristics of planar granular assemblies: self-organisation and scaling away friction and initial state
Takashi Matsushima, Raphael Blumenfeld
We identify the fundamental factors determining the microstructural (MS) statistics of granular systems, using numerical experiments on 2D assemblies of polydisperse frictional dis…
