Collisional regime during the discharge of a 2D silo
Roberto Arévalo
The present work reports a novel investigation into the collisional dynamics of particles in the vicinity of the outlet of a 2D silo using molecular dynamics simulations. Most stud…
A topological method to characterize tapped granular media from the position of the particles
Sergio Ardanza-Trevijano, Iker Zuriguel, Roberto Arevalo +1
We use the first Betti number of a complex to characterize the morphological structure of granular samples in mechanical equilibrium. We analyze two-dimensional granular packings a…
Size and density avalanche scaling near jamming
Roberto Arévalo, Massimo Pica Ciamarra
The current microscopic picture of plasticity in amorphous materials assumes local failure events to produce displacement fields complying with linear elasticity. Indeed, the flow…
The flow rate of granular materials through an orifice
C. Mankoc, A. Janda, R. Arévalo +4
The flow rate of grains through large orifices is known to be dependent on its diameter to a 5/2 power law. This relationship has been checked for big outlet sizes, whereas an empi…
Identification of arches in 2D granular packings
Roberto Arevalo, Luis A. Pugnaloni, Diego Maza
We identify arches in a bed of granular disks generated by a molecular dynamic-type simulation. We use the history of the deposition of the particles to identify the supporting con…
