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…
