WHEN FAILURE IS AN OPTION: REWIRING GRANULAR NETWORKS
Summary We report on recent advances in the multiscale analysis of emergent networks in deforming, dense granular assemblies. Conceptually, we envision the material as an evolving mathematical graph or network that is employing specific rules in adapting its contact and contact force networks in response to applied loads. In this context, the question that arises is: Is the granular material re-wiring its networks to optimize a particular measure and, if so, what is this measure? We probe this question within a multidisciplinary framework. Synergistic blends of techniques from Structural Mechanics, Complex Networks and Dynamical Systems are employed to uncover clues on self-organized pattern formation in the lead up to and during failure. We demonstrate these techniques by analysing data from various compression tests, both from discrete element simulations and physical experiments on photoelastic disks.
