Abstract

Techniques from Complex Networks are used to study the evolving
topology and functional connectivity in various granular systems in both two and
three dimensions. A generic process of self-organization in all samples is realized
and is characterized by the co-evolutionary synergy between force chains and
3-cycles. Three-cycles provide force chains a twofold benefit: (i) they prop-up force
chains in the way that a counterfort or buttress supports a wall, and (ii) they frustrate
rolling at contacts which is a critical mechanism for buckling. All samples reflect an
inherent structural hierarchy where cyclic (minimal cycles) and linear (force chains)
motifs of various length scales serve as basic building blocks for self-organization.
