2D Numerical Modeling of Soil Behavior under Drained Tri-axial loading with Discrete Element Method

The purpose of the present study is to evaluate mechanical {stress-strain and volumetric} behavior of granular materials considering their internal physical properties in particle scale. To this end, two-dimensional numerical modeling of drained compressive tri-axial te¬st, using Discrete Element Method (DEM) was utilized. DEM-2D computer code was adopted for modeling these tests based on Discrete Element Method formulation. Drained biaxial numerical tests on specimens with different void ratios and confining pressures were carried out and the results are compared with the associated laboratory tests results reported in the literature.
