Abstract : The aim of this study is the modeling of the fragmentation of granular material subjected to compressive loading by using Discrete Element Method DEM. The proposed model depends mainly on two mechanical aspects which are: the mechanical behavior of the granular material and the yield strength predicting the fragmentation of grains. In order to better understand the mechanical phenomena, we have studied the contact force chains according to the granulometry of the material and the fragmentation modes of grains. The proposed modeling has been tested on a numerical simulation of oedometric test by using our software MULTICOR.

Keywords : granular material DEM fragmentation strength criteria
