Shear Is Not Always Simple: Rate-Dependent Effects of Flow Type on Granular Rheology
Joel T. Clemmer, Ishan Srivastava, Gary S. Grest +1
Despite there being an infinite variety of types of flow, most rheological studies focus on a single type such as simple shear. Using discrete element simulations, we explore bulk…
Jamming of Bidisperse Frictional Spheres
Ishan Srivastava, Scott A. Roberts, Joel T. Clemmer +3
By generalizing a geometric argument for frictionless spheres, a model is proposed for the jamming density of mechanically stable packings of bidisperse, frictional spheres.…
Criticality in sheared, disordered solids. II. Correlations in avalanche dynamics
Joel T. Clemmer, K. Michael Salerno, Mark O. Robbins
Disordered solids respond to quasistatic shear with intermittent avalanches of plastic activity, an example of the crackling noise observed in many nonequilibrium critical systems.…
Criticality in sheared, disordered solids. I. Rate effects in stress and diffusion
Joel T. Clemmer, K. Michael Salerno, Mark O. Robbins
Rate-effects in sheared disordered solids are studied using molecular dynamics simulations of binary Lennard-Jones glasses in two and three dimensions. In the quasistatic (QS) regi…
