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