Three-Dimensional DEM Modeling of Triaxial Compression of Sands
The three-dimensional discrete element method code (PFC3D) was used to model triaxial compression tests on sands and the results were compared with physical laboratory tests. The sand particles were modeled by unbreakable 2-sphere clumps, so that interlocking between particles, which yielded more stable and efficient force chains, could take place. This was confirmed by comparing the results modeled by 2-sphere clumps with the results of tests where particles were modeled by single spheres. In addition to global stress and strain response, void ratios and coordination numbers were monitored at different locations within the specimens throughout the shearing process, and their evolution was evaluated to see whether localization existed within the specimens.
