Wang-Landau algorithm for entropic sampling of arch-based microstates in the volume ensemble of static granular packings
(Instituto de Física de Líquidos y Sistemas Biológicos, 2015-03)
We implement the Wang-Landau algorithm to sample with equal probabilities the static configurations of a model granular system. The “non-interacting rigid arch model" used is based on the description of static configurations ...
Dynamic behavior of humid granular avalanches: Optical measurements to characterize the precursor activity
(American Physical Society, 2020-02)
Laboratory study of slope stability of granular media remains a challenge for modeling, understanding, and predicting natural hazards, such as avalanches and landslides, precursory signs of which are controlled by numerous ...

Arch-based configurations in the volume ensemble of static granular systems
(IOP Publishing, 2015-02-03)
We propose an alternative approach to count the microscopic static configurations of granular packs under gravity by considering arches. This strategy obviates the problem of filtering out configurations that are not ...
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 ...
The effect of blending granular aggregates of different origin on the strength of concrete
(Elsevier Science, 2012-03-01)
This work correlates the resistance of concrete cores with the physical properties of the granular material forming it. A basic physical characterization is conducted, taking into account the origin of the grains involved ...
Simulation of granular compacts in two dimensions
(Springer, 2001-03)
Simulations of granular packings in 2-D by throwing disks in a rectangular die are performed. Different size distributions as bimodal, uniform and gaussian are used. Once the array of particles is done, a relaxation process ...
Tapped granular packings described as complex networks
(Taylor & Francis, 2013-06)
We characterize the structure of simulated two-dimensional granular packings using concepts from complex networks theory. The packings are generated by a simulated tapping protocol, which allows us to obtain states in ...
