In this study, a spherical projectile vertical impact into a granular bed was numerically investigated with 3D Discrete Element Method (DEM) and validated with experiments. We vary the impact velocity (0.9–3.6m/s) and size of particles in the bed (1–3mm) and study the changes in ejecta velocity distribution for different impacts. We find good agreement for the total ejecta mass and for the velocity...
Discrete element simulations, with the particle–particle interaction model based on classical contact mechanics theory between two non-adhesive spheres, were carried out and compared with ‘sandpile’ experiments using spherical particles in order to assess the validation of the simulation data. The contact interaction model is a combination of Hertzian theory for the normal interaction and Mindlin–Deresiewicz...
