abstract = "ESyS-Particle, the 3-D Discrete Element Model, is used to model the fracture process and the size distribution of rock fragmentation under two different loading conditions: 1) Slow uni-axial compression of a ball aggregate which consists of small bonded particles; 2) Impact of a ball consisting of bonded particles to a stiff wall. We reproduce the realistic fracture patterns, such as meridional cracks under slow loading and secondary cracks under fast loading. We observe a transition from damage to fragmentation as impact velocity increases. The latter one is characterized by generation of fines and a power law distribution of fragment sizes.",
