Statistical admissibility and long-wavelength structural convergence determine representative support in granular materials
Fernando Alonso-Marroquin, Abdullah Alqubalee, Eduardo Garzanti +1
Representative elementary areas and volumes provide the scale bridge between resolved granular microstructure and continuum-scale material properties, yet they are still commonly s…
3D Molecular dynamics simulations using spheropolytopes
Sergio-Andres Galindo-Torres, Fernando Alonso-Marroquin, Yucang Wang
We present a simple and efficient method to simulate three-dimensional, complex-shaped, interacting bodies. The particle shape is represented by Minkowski operators. A time-continu…
An efficient algorithm for granular dynamics simulation with complex-shaped objects
F. Alonso-Marroquin, Yucang Wang
The most difficult aspect of the realistic modeling of granular materials is how to capture the real shape of the particles. Here we present a method to simulate granular materials…
Effect of rolling on dissipation in fault gouge
F Alonso-Marroquin, I. Vardoulakis, H. J. Herrmann +2
Sliding and rolling are two outstanding deformation modes in granular media. The first one induces frictional dissipation whereas the latter one involves deformation with negligibl…
The anisotropy of granular materials
F. Alonso-Marroquin, S. Luding, H. J. Herrmann
The effect of the anisotropy on the elastoplastic response of two dimensional packed samples of polygons is investigated here, using molecular dynamics simulation. We show a correl…
Calculation of the incremental stress-strain relation of a polygonal packing
F. Alonso-Marroquin, H. J. Herrmann
The constitutive relation of the quasi-static deformation on two dimensional packed samples of polygons is calculated using molecular dynamic simulations. The stress values at whic…
