Tapped granular packings described as complex networks
(Taylor and Francis, 2013)We characterize the structure of simulated two-dimensional granular packings using con- cepts from complex networks theory. The packings are generated by a simulated tapping protocol, which allows us to obtain states in ... -
Two approaches to quantification of force networks in particulate systems
(2021-02-24)The interactions between particles in particulate systems are organized in ‘force networks’, mesoscale features that bridge between the particle scale and the scale of the system as a whole. While such networks are known ... -
Universal features of the stick-slip dynamics of an intruder moving through a confined granular medium
(2022-04-21)Experiments and simulations of an intruder dragged by a spring through a two-dimensional annulus of granular material exhibit robust force fluctuations. At low packing fractions (φ < φ0), the intruder clears an open ... -
Wang Landau algorithm for entropic sampling of arch based microstates in the volume ensemble of static granular packings
(Papers in Physics, 2015)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 ...
