Controlled viscosity in dense granular materials
A. Gnoli, L. de Arcangelis, F. Giacco +4
We experimentally investigate the fluidization of a granular material subject to mechanical vibrations by monitoring the angular velocity of a vane suspended in the medium and driv…

Rattler-induced aging dynamics in jammed granular systems
Ferdinando Giacco, Lucilla de Arcangelis, Massimo Pica Ciamarra +1
Granular materials jam when developing a network of contact forces able to resist the applied stresses. Through numerical simulations of the dynamics of the jamming process, we sho…
