Granular materials composed of particles with differing grain sizes, densities, shapes, or
surface properties may experience unexpected segregation during flow. This review focuses …

Predicting the morphodynamics of sedimentary landscapes due to fluvial and aeolian flows
requires answering the following questions: Is the flow strong enough to initiate sediment …

Limbless organisms such as snakes can navigate nearly all terrain. In particular, desert-
dwelling sidewinder rattlesnakes (Crotalus cerastes) operate effectively on inclined granular …

This review article provides an overview of dry granular flows and particle fluid mixtures,
including experimental and numerical modeling at the laboratory scale, large scale …

Guided by a series of discriminating rheometric tests, we develop a new constitutive model
that can quantitatively predict the key rheological features of waxy crude oils. We first …

We propose and numerically implement a constitutive framework for granular media that
allows the material to traverse through its many common phases during the flow process …

The rheology of dense granular flows is studied numerically in a shear cell controlled at
constant pressure and shear stress, confined between two granular shear flows. We show …

This review focuses on how the modeling of dense granular media has advanced over the
last 15 years. The jumping-off point of our review is the μ (I) rheology for dry granular flow …

Based on discrete element method simulations, we propose a new form of the constitutive
equation for granular flows independent of packing fraction. Rescaling the stress ratio μ by a …

A recent granular rheology based on an implicit “granular fluidity” field has been shown to
quantitatively predict many nonlocal phenomena. However, the physical nature of the field …
