Sliding Blocks Revisited: A simulational Study
A. R. de Lima, C. Moukarzel, T. J. P. Penna
A computational study of sliding blocks on inclined surfaces is presented. Assuming that the friction coefficient is a function of position, the probability for the bloc…
Floppy modes and the free energy: Rigidity and connectivity percolation on Bethe Lattices
P. M. Duxbury, D. J. Jacobs, M. F. Thorpe +1
We show that negative of the number of floppy modes behaves as a free energy for both connectivity and rigidity percolation, and we illustrate this result using Bethe lattices. The…
Reply to the comment by Jacobs and Thorpe
Phillip M. Duxbury, Cristian F. Moukarzel, Paul L. Leath
Reply to a comment on "Infinite-Cluster geometry in central-force networks", PRL 78 (1997), 1480. A discussion about the order of the rigidity percolation transition.
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…
Isostatic phase transition and instability in stiff granular materials
Cristian F. Moukarzel
In this letter, structural rigidity concepts are used to understand the origin of instabilities in granular aggregates. It is shown that: a) The contact network of a noncohesive gr…
A fast algorithm for backbones
Cristian F. Moukarzel
A matching algorithm for the identification of backbones in percolation problems is introduced. Using this procedure, percolation backbones are studied in two- to five-dimensional…
