Summary In the absence of initial cracks, the material behavior is limited by its strength, usually defined in homogeneous conditions (of stress and strain). Beyond this limit, in quasi-brittle case, cracks may propagate and the material behavior ten

Summary We propose a discrete element model for brittle rupture. The material consists of a bidimensional set of closed-packed particles in contact. We explore the isotropic elastic behavior of this regular structure to derive a rupture criterion com
