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

Designing architectural materials: from granular form to functional granular material
Bioinspiration & Biomimetics, 2021 Abstract Designed granular materials are a novel class of architectural material system. Following one of the key paradigms of designed matter, material form and material function are closely interrelated in these systems. In this context, the article aims to contribute a parametric particle design model as an interface for this ...

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 ...

The variation of grain size distribution in rock granular material in seepage process considering the mechanical–hydrological–chemical coupling effect: an experimental research [PDF]
Royal Society Open Science, 2020 As a common solid waste in geotechnical engineering, rock granular material should be properly treated and recycled. Rock granular material often coexists with water when it is used as the filling material in geotechnical engineering.

Memory Effects in Granular Materials [PDF]
Physical Review Letters, 2000 We present a combined experimental and theoretical study of memory effects in vibration-induced compaction of granular materials. In particular, the response of the system to an abrupt change in shaking intensity is measured. At short times after the perturbation a granular analog of aging in glasses is observed.
