The effect of particle aspect ratio and surface geometry on granular flows is assessed by
performing numerical simulations of rod-like particles in simple shear flows using the …

This paper presents a model which can be used for fast landslides where coupling between
solid and pore fluid plays a fundamental role. The proposed model is able to describe debris …

In the present paper, flows of granular materials impacting wall-like obstacles down inclines
are described by depth-averaged analytic solutions. Particular attention is paid to extending …

Granular shear flows of flat disks and elongated rods are simulated using the Discrete
Element Method. The effects of particle shape, interparticle friction, coefficient of restitution …

The local granular rheology is investigated numerically in turbulent bedload transport.
Considering spherical particles, steady uniform configurations are simulated using a …

The steady-state shear rheology of granular materials is investigated in slow quasistatic and
inertial flows. The effect of gravity (thus the local pressure) and the often-neglected contact …

We propose a constitutive model for both the solid-like and fluid-like behavior of granular
materials by decomposing the stress tensor into quasi-static and collisional components. A …

We use previous results from discrete element simulations of simple shear flows of rigid,
identical spheres in the collisional regime to show that the volume fraction-dependence of …

We extend models for granular flows based on the kinetic theory beyond the critical volume
fraction at which a rate-independent contribution to the stresses develops. This involves the …

During heating (loading characterised by a progressive increase in strain rate) and cooling
(loading characterised by a progressive decrease in strain rate) numerical tests, performed …
