Abstract: P56.00012 : The Duality of Networks in Jammed Granular Packings*
5:06 PM–5:18 PM
Using jammed granular packings obtained from simulations, we explore the duality between the resultant real-space contact networks and force tilings. We analyze the relationship between zero modes and states of self-stress in these dual networks, and connect it to physical properties of jammed packings and to unjamming. In particular, this can provide improved understanding of the stability of granular systems against the effect of external perturbations.
