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…
Dynamical noise and avalanches in quasi-static plastic flow of amorphous solids
Anaël Lemaître, Christiane Caroli
We build a mean-field model of plasticity of amorphous solids, based on the dynamics of an ensemble shear transformation zones, interacting via intrinsic dynamical noise generated…
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,…
