Abstract
Résumé

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.

Les récents progrès dans la compréhension des écoulements granulaires denses sont passés en revue, en nous focalisant sur la rhéologie classique des matériaux granulaires, tout en affinant notamment au niveau des effets non locaux, de l'influence des conditions aux limites des écoulements et de l'évolution des propriétés d'écoulement des systèmes hétérogènes.
