The fragmentation of materials is a phenomenon which arises in several natural and industrial systems, and for a wide range of scales. From an industrial point of view, the crushing process is very important in the production of aggregates, which are often required to meet high criteria in terms of size and shape. However, the phenomena behind fracture of materials are still not completely understood. The discrete element methods allow to model interactions at the scale of the material micro-structure, by means of simple models. One of the advantages of this kind of methods is the natural way the crack initiates and propagates in the sample, without any need of a crack model. A discrete element model allowing to describe cohesion inside the...
