Stresses in Isostatic Granular Systems and Emergence of Force Chains
Stresses in Isostatic Granular Systems and Emergence of Force Chains
Progress is reported on several questions that bedevil understanding of granular systems: (i) are the stress equations elliptic, parabolic or hyperbolic? (ii) how can the often-observed force chains be predicted from a first-principles continuous theory? (iii) How to relate insight from isostatic systems to general packings? Explicit equations are derived …
