Abstract

A numerical model based on a three dimensional Discrete Element Method (DEM) has been used to study the behavior of cohesive granular geomaterials such as concrete under a high confining pressure (up to 650 MPa). At this range of pressures, irreversible compaction of the material occurs and needs to be considered. Within the discontinuous nature of the model, a local constitutive law has been developed to re- produce this phenomenon quantitatively.
