Granular matter instability: A structural rigidity point of view
Cristian F. Moukarzel
Stress paths in granular matter often suffer sudden large-scale rearrangements when the system is slightly perturbed, i.e. granular systems are unstable. We show in this paper that…

Comparison of connectivity and rigidity percolation
Cristian F. Moukarzel, Phillip M. Duxbury
We summarize ideas and methods that apply to rigidity and connectivity percolation. These include: constraint counting concepts, exact calculations on diluted trees and numerical r…
