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…
Modeling slow deformation of polygonal particles using DEM
Andres A. Pena, Pedro G. Lind, Hans J. Herrmann
We introduce two improvements in the numerical scheme to simulate collision and slow shearing of irregular particles. First, we propose an alternative approach based on simple rela…
Numerical Improvement of the Discrete Element Method applied to Shear of Granular Media
Andrés A. Peña, Pedro G. Lind, Sean McNamara +1
We present a detailed analysis of the bounds on the integration step in Discrete Element Method (DEM) for simulating collisions and shearing of granular assemblies. We show that, i…
Influence of particle shape on sheared dense granular media
A. A. Peña, R. García-Rojo, H. J. Herrmann
We study by means of molecular dynamics simulations of periodic shear cells, the influence of particle shape on the global mechanical behavior of dense granular media. Results at m…
