Percolation of a rod-like particle in a static bed of spheres: trapping and passing
Juan C. Petit, Julio M. Ottino, Richard M. Lueptow +1
We numerically investigate percolation of independent frictionless glued-sphere rod-like particles under gravity through a disordered static bed of larger spheres. We identify two…
Additional jamming transition in 2D bidisperse granular packings
Juan C. Petit, Matthias Sperl
We present a jamming diagram for 2D bidisperse granular systems, capturing two distinct jamming transitions. The first occurs as large particles form a jammed structure, while the…
Vibrational similarities in jamming-unjamming of polycrystalline and disordered granular packings
Juan C. Petit, Saswati Ganguly, Matthias Sperl
We investigate the vibrational properties of polycrystalline monodisperse and disordered bidisperse granular packings during jamming and unjamming using discrete element method sim…
Confined granular gases under the influence of vibrating walls
M. Mayo, J. C. Petit, M. I. García de Soria +1
The dynamics of a system composed of inelastic hard spheres or disks that are confined between two parallel vertically vibrating walls is studied (the vertical direction is defined…
Structural transitions in jammed asymmetric bidisperse granular packings
Juan C. Petit, Matthias Sperl
We study the local structural changes along the jamming transitions in asymmetric bidisperse granu\-lar packings. The local structure of the packing is assessed by the contact orie…
Bulk Modulus along Jamming Transition Lines of Bidisperse Granular Packings
Juan C. Petit, Nishant Kumar, Stefan Luding +1
We present 3D DEM simulations of bidisperse granular packings to investigate their jamming densities, , and dimensionless bulk moduli, , as a function of the size ratio, $δ…
Additional transition line in jammed asymmetric bidisperse granular packings
Juan C. Petit, Nishant Kumar, Stefan Luding +1
We present numerical evidence for an additional discontinuous transition inside the jammed regime for an asymmetric bidisperse granular packing upon compression. This additional tr…
Reduction of the bulk modulus with polydispersity in non-cohesive granular solids
Juan C. Petit, Ernesto Medina
We study the effect of grain polydispersity on the bulk modulus in non-cohesive two dimensional granular solids. Molecular dynamics simulations in two dimensions are used to descri…
Contact angle entropy and macroscopic friction in non-cohesive two dimensional granular packings
Juan C. P. Petit, Xavier García, Iván Sánchez +1
We study the relationship between the granular contact angle distribution and local particle friction on the macroscopic friction and bulk modulus in non-cohesive disk packings. Mo…
