MGC2D

Solid bonding DEM

Jean-Yves Delenne

1 General overview

MGC-2D is a 2D command line utility designed to compute the mechanical behavior of granular aggregates. This code, written in C, is based on theMolecular Dynamics (MD) method. It can take into account various interaction laws (contact, friction, adhesion), but its originality lies in its ability to account for solid bonding between particles. It can also handle thermodynamic parameters such as the damage of the bonds or swelling and shrinking of particles.
