The discontinuous Galerkin formulation provides an efficient scalable framework to simulate non-linear dynamics of spatially discontinuous structures. Cracks can initiate at any element boundary and evolve driven by a cohesive law. A DG-cohesive weak formulation is derived, implemented into a parallel finite element code, and applied to the fragmentation of a three-dimensional plate submitted to biaxial tension.Discontinuous Galerkin methodexplicit time integrationcohesive elementsfrag- mentationheterogeneous materials.text::conference output::conference paper not in proceedings
