Dilatancy in dry granular flows with a compressible μ(I) rheology
(Elsevier, 2021)
Dilatancy plays a key role in mixtures of grains and fluid but is poorly investigated in dry granular flows. These flows may however dilate by more than 10% in granular column collapses. We investigate here dilatancy effects ...

A bed pressure correction of the friction term for depth-averaged granular flow models
(Elsevier, 2022)
Depth-averaged models, such as the Savage-Hutter model with Coulomb or Pouliquen fric tion laws, do not in some cases preserve the physical threshold of motion. In particular, the simulated granular mass can start to flow ...
