Thermal shakedown in granular materials with irregular particle shapes [PDF]
Scientific ReportsGranular materials with irregular particle shapes undergo a myriad of temperature variations in natural and engineered systems. However, the impacts of cyclic temperature variations on the mechanics of granular materials remain poorly understood ...

Liquid migration in flowing granular materials [PDF]
EPJ Web of Conferences, 2021 In partially wet granular beds, liquid migrates between particles due to collisions and contacts. This, in turn, influences the flow behaviour of the granular bed.

Mesoscale inertial transition in granular materials [PDF]
EPJ Web of Conferences, 2021 Granular assemblies can experience complex failure patterns along a given loading path, with a distribution of ephemeral inertial events marked by local outbursts in kinetic energy.

Flow in an hourglass: particle friction and stiffness matter
New Journal of Physics, 2021 Granular flow out of a silo is studied experimentally and numerically. The time evolution of the discharge rate as well as the normal force (apparent weight) at the bottom of the container is monitored. We show that particle stiffness has a strong effect

The role of the particle aspect ratio in the discharge of a narrow silo
New Journal of Physics, 2022 The time evolution of silo discharge is investigated for different granular materials made of spherical or elongated grains in laboratory experiments and with discrete element model (DEM) calculations.

Rheology of two-dimensional crushable granular materials [PDF]
EPJ Web of Conferences, 2021 The rheology of two-dimensional crushable granular materials under shear is numerically studied using the discrete element method. We find that the mean fragment size changes as the shear strain increases while the shear stress is almost independent of ...

Rheology of soft granular materials: uniaxial compression [PDF]
EPJ Web of Conferences, 2021 Soft granular materials are assemblies of highly deformable grains interacting via surface forces. The large grain deformations of these materials differ them from hard granular systems, in which, their behaviors are essentially governed by grain ...
