DEM for Modeling Cracks Propagation in Rocks under Uniaxial Compression Tests

The Discrete Element Method (DEM) was used to simulate cracks propagate in rocks subjected to uniaxial compressive stress. A DEM code was developed, and used to simulate the response of the continuum materials to loading. Rock samples with two initial cracks inclined at varying angles were simulated with the DEM code. The results were compared with those obtained from laboratory samples, and it was observed that the two results were consistent. This suggests that the DEM is a robust technique for the visualization of secondary cracks formations and propagations in rocks.
