%0 Journal Article %T Rheological properties of dense granular flows %A Pierre Jop %J Physics %D 2015 %I arXiv %R 10.1016/j.crhy.2014.12.001 %X Recent progresses in understanding the behavior of dense granular flows are presented. After presenting a bulk rheology of granular materials, I focus on the new developments to account for non-local effects, and on ongoing research concerning the surface rheology and the evolution of mechanical properties for heterogeneous systems. %U http://arxiv.org/abs/1503.05452v1
