A Hydrodynamic model for a dynamical jammed-to-flowing transition in gravity driven granular media

, 2001
Granular material on an inclined plane will flow like a fluid if the angle $\theta$ the plane makes with the horizontal is large enough. We employ a modification of a hydrodynamic model introduced previously to describe Couette flow experiments to ...

Slow flows of yield stress fluids: complex spatio-temporal behaviour within a simple elasto-plastic model

, 2004
A minimal athermal model for the flow of dense disordered materials is proposed, based on two generic ingredients: local plastic events occuring above a microscopic yield stress, and the non-local elastic release of the stress these events induce in the ...
