10 W H I T E P A P E R Figure 7: Example of a glass bead being broken into smaller fragments using the discrete breakage approach. The strength and breakage propensity of a shaped particle is quite different from that observed in a glued spheres particle, highlighting the advantage of Rocky's particle representation for breakage analysis. With a 3D polyhedral shape, the mass and size of fragments account for stresses at the contact points, and these results aren't predetermined by the size and number of spheres around the contact points. Furthermore, Rocky's discrete particle breakage takes into account the particle's collision locations and their internal stresses, capturing shape-dependent breakage and crack propagation. 4 FINAL REMARKS Regardless of the particle shape or the application being analyzed, Rocky DEM has the appropriate breakage model for you, and all models are capable of preserving the mass and volume of the original particle. The Ab-T10 and the Tavares models allow the representation of hard materials' brittle breakage, producing randomly shaped fragments with smaller fragments being generated closer to the impact point. In addition, Rocky's unique discrete breakage model is a high-fidelity model that considers the collision location at the particle's surface along with its consequent internal stresses, capturing shape-dependent breakage and crack propagation.
