Investigation of particle shape and ambient fluid on sandpiles using a coupled micro-geomechanical model

Particle motion in granular systems is common nature and industrial processes. Along with particle size density, the shape of particles also plays a crucial role dynamic behavior such systems. To capture irregular morphology particles, we have proposed an image-based discrete element method which effect fluid considered. We considered four cases to study how ambient simultaneously affect properties sandpiles, that dry water-immersed for both spherical particles. found repose angle sandpiles increased models while decreased by having water system. The contact force chains are stronger than sandpiles. Meanwhile, weakened water. Furthermore, largest displacement occurs sandpile immersed
