Rheology of Frictional Particles — •Matthias Grob1, Claus Heussinger1, and Annette Zippelius1,2 — 1Institut für Theoretische Physik, Göttingen, Deutschland — 2Max-Planck-Institut für Dynamik und Selbstorganisation, Göttingen, Deutschland
Granular materials are complex fluids with the ability to jam into a solid state. The properties of the jamming transition depend in addition to packing fraction and shear rate on the presence or absence of inter-particle friction. Here, jamming of frictional particles under simple shear is investigated numerically. Various regimes and transitions are observed and discussed. These transitions are influenced by the three control parameters. We find shear banding for dense systems within a certain range of shear rates and coexistence between solid and fluid like states.
