Force Attractor in Confined Comminution of Granular Materials
Force Attractor in Confined Comminution of Granular Materials Ben-Nun, O., Einav, I., Tordesillas, A., 2010 Phys. Rev. Lett. 104, 108001 – 108004 Published 8 March 2010 | DOI: https://doi.org/10.1103/PhysRevLett.104.108001 ABSTRACT We reveal a novel attractor in the space of contact forces that bounds the behavior of granular materials during confined comminution. The attractor is reached
The role of self-organisation during confined comminution of granular materials
The role of self-organization during confined comminution of granular materials Ben-Nun, O., Einav, I., 2010.Phil. Trans. Roy. Soc. A, 368, 231-247.Published: 13 January 2010 | https://doi.org/10.1098/rsta.2009.0205 Abstract During confined comminution of granular materials a power-law grain size distribution (gsd) frequently evolves. We consider this power law as a hint for fractal topology if self-similar patterns appear across
