Abstract

We propose a method for the simulation of particle fragmentation based on the calculation of the strain energy field inside the particle. The topography of strain energy is calculated in terms of internal stress using the principles of damage and fracture mechanics. Numerical calculation of the energy field’s ridges is used to determine the breakage criterion as well as the shape of the post-breakage fragments. This method provides a physical-based understanding of the breakage effect in granular material.
