Eshelby inclusions in granular matter: theory and simulations
Sean Mcnamara, Jérôme Crassous, Axelle Amon
We present a numerical implementation of an active inclusion in a granular material submitted to a biaxial test. We discuss the dependence of the response to this perturbation on t…
On the relevance of numerical simulations to booming sand
Patrick Richard, Sean Mcnamara, Merline Tankeo
We have performed a simulation study of 3D cohesionless granular flows down an inclined chute. We find that the oscillations observed in [L.E. Silbert, Phys. Rev. Lett., 94, 098002…
Aspects of weakening in granular assemblies
Philipp Welker, Sean McNamara
We study numerical simulations of large (N~10^4) two-dimensional quasi-static granular assemblies subjected to a slowly increasing deviator stress. We report some peculiarities in…
Avalanches in anisotropic sheared granular media
Andrés A. Peña, Sean McNamara, Pedro G. Lind +1
We study the influence of particle shape anisotropy on the occurrence of avalanches in sheared granular media. We use molecular dynamic simulations to calculate the relative moveme…
Microscopic origin of granular ratcheting
S. McNamara, R. García-Rojo, H. J. Herrmann
Numerical simulations of assemblies of grains under cyclic loading exhibit ``granular ratcheting'': a small net deformation occurs with each cycle, leading to a linear accumulation…
Study of sediment transport in the saltation regime
F. Osanloo, M. R. Kolahchi, S. McNamara +1
We present a study of sediment transport in the creeping and saltation regime. In our model, a bed of particles is simulated with the conventional event-driven method. The particle…
