Modelagem física de colunas granulares compactadas de RCC parcialmente reforçadas com geossintéticos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Civil - PPGECivCâmpus São Carlos, 2019-03-14)
Granular Columns has been intensively used as soil improvement for spread footings, embankments and other applications. The filling material of columns is generally crushed stone or sand. However, replacing these natural ...
Exact predictions from Edwards ensemble vs realistic simulations of tapped narrow two dimensional granular columns

Exact predictions from the Edwards ensemble versus realistic simulations of tapped narrow two-dimensional granular columns
(IOP Publishing, 2013-12)
We simulate, via a discrete element method, the tapping of a narrow column of disks under gravity. For frictionless disks, this system has a simple analytical expression for the density of states in the Edwards volume ...
Relevance of system size to the steady-state properties of tapped granular systems
(American Physical Society, 2015-03)
We investigate the steady-state packing fraction phi and force moment tensor of quasi-two-dimensional granular columns subjected to tapping. Systems of different height h and width L are considered. We find that<br />phi ...

Forced flow of granular media: Breakdown of the Beverloo scaling
(Europhysics Letters, 2018-08)
The Beverloo scaling for the gravity flow of granular materials through orifices has two distinct universal features. On the one hand, the flow rate is independent of the height of the granular column. On the other hand, ...
Ergodic-nonergodic transition in tapped granular systems: The role of persistent contacts
(Instituto de Física de Líquidos y Sistemas Biológicos, 2016-01)
Static granular packs have been studied in the last three decades in the frame of a modified equilibrium statistical mechanics that assumes ergodicity as a basic postulate. The canonical example on which this framework is ...
