The jamming transition and new percolation universality classes in particulate systems with attraction
Gregg Lois, Jerzy Blawzdziewicz, Corey S. O'Hern
We numerically study the jamming transition in particulate systems with attraction by investigating their mechanical response at zero temperature. We find three regimes of mechanic…
Force networks and the dynamic approach to jamming in sheared granular media
Gregg Lois, Jean M. Carlson
Diverging correlation lengths on either side of the jamming transition are used to formulate a rheological model of granular shear flow, based on the propagation of stress through…
Long Range Correlation in Granular Shear Flow II: Theoretical Implications
Gregg Lois, Anael Lemaitre, Jean M. Carlson
Numerical simulations are used to test the kinetic theory constitutive relations of inertial granular shear flow. These predictions are shown to be accurate in the dilute regime, w…
Long Range Correlations in Granular Shear Flow I: Numerical Evidence
Gregg Lois, Anael Lemaitre, Jean M. Carlson
We investigate the emergence of long-range correlations in granular shear flow. By increasing the density of a simulated granular flow we observe a spontaneous transition from a di…
Momentum Transport in Granular Flows
Gregg Lois, Anael Lemaitre, Jean M. Carlson
We investigate the error induced by only considering binary collisions in the momentum transport of hard-sphere granular materials, as is done in kinetic theories. In this process,…
Numerical Tests of Constitutive Laws for Dense Granular Flows
Gregg Lois, Anaël Lemaître, Jean M. Carlson
We numerically and theoretically study macroscopic properties of dense, sheared granular materials. In this process we first introduce an invariance in Newton's equations, explain…
