Grain fragmentation in sheared granular flow: weakening effects, energy dissipation, and strain localization
Charles K. C. Lieou, Ahmed E. Elbanna, Jean M. Carlson
We describe the shear flow of a disordered granular material in the presence of grain fracture using the shear-transformation-zone (STZ) theory of amorphous plasticity adapted to s…
Sacrificial bonds and hidden length in biomaterials -- a kinetic, constitutive description of strength and toughness in bone
Charles K. C. Lieou, Ahmed E. Elbanna, Jean M. Carlson
Sacrificial bonds and hidden length in structural molecules account for the greatly increased fracture toughness of biological materials compared to synthetic materials without suc…
Descriptor approach for eliminating spurious eigenvalues in hydrodynamic equations
M. Lisa Manning, B. Bamieh, J. M. Carlson
We describe a general framework for avoiding spurious eigenvalues -- unphysical unstable eigenvalues that often occur in hydrodynamic stability problems. In two example problems, w…
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,…
