  • Stress correlations in granular materials: An entropic formulation
    Zhang, J.; Majmudar, T. S.; Behringer, Robert (AMER PHYSICAL SOC, 2009)
    We study the response of dry granular materials to external stress using experiment, simulation, and theory. We derive a Ginzburg-Landau functional that enforces mechanical stability and positivity of contact forces. In ...
