We investigate the failure behavior of dense brittle materials based on a discrete element simulation. The model is applied to situations of uniaxial strain loading of a dense cohesive brittle material (i.e. ceramics or concrete). The results exhibit that the model is capable of reproducing the salient features of the material expressed in a few parameters and the fracture patterns.
