Discrete element modelling of granular materials incorporating realistic particle shapes

Abstract This paper proposes an approach to generate realistic particle shapes considering the major plane of orientation particles in discrete element modelling (DEM). The generation framework includes capturing high-quality scanning electron microscope (SEM) images, followed by image processing and clumps using a commonly used multi-sphere (MS) flow code (PFC3D). A set experimental direct shear tests (DST) subsequent DEM simulations were performed incorporating shapes. simulation results show good agreement with those obtained laboratory. In addition, normal stress showed significant effect on structural anisotropy granular materials.
