Deformability of Discrete Elements

Abstract

The Discrete Element Method (DEM) appears as one of the most attractive methods for understanding general geotechnical problems and specifically the behavior of rocks due to their unique advantages in dealing with fracturing processes. In this work, unconfined compression and indirect tensile tests were performed for a magmatic rock, known as Lac du Bonnet granite, based on a discrete approach using DEM and a specific contact and cementation model between the particles. Concluding, a parametric analysis of the influence of Young's modulus on some macroscopic properties of the rock's numerical model was carried out, with the objective of generating contributions as to the understanding of the deformability and strength behavior of hard rocks.
