Structure of force networks in tapped particulate systems of disks and pentagons I Clusters and loops
(American Physical Society, 2016)
The force network of a granular assembly, defined by the contact network and the corresponding contact
forces, carries valuable information about the state of the packing. Simple analysis of these networks based on the ...
Effect of particle shape and fragmentation on the response of particle dampers
(SAGE Publications, 2014)
A particle damper (PD) is a device that can attenuate mechanical vibrations thanks to the dissipative collisions between grains contained in a cavity attached to the vibrating structure. It has been recently suggested that, ...
Structure of force networks in tapped particulate systems of disks and pentagons II Persistence analysis
(American Physical Society, 2016)
In the companion paper [Pugnaloni et al., Phys. Rev. E 93, 062902 (2016)], we use classical measures based on force probability density functions (PDFs), as well as Betti numbers (quantifying the number of components, ...
Flow rate of polygonal grains through a bottleneck Interplay between shape and size
(Papers in Physics, 2015)
We report two-dimensional simulations of circular and polygonal grains passing through an aperture at the bottom of a silo. The mass flow rate for regular polygons is lower than for disks\red{,} as observed by other authors. ...
