Discontinuous Galerkin method applied to fragmentation of heterogeneous materials

Résumé

Since it generates a multitude of interacting cracks, the computational modeling of fragmentation requires special attention. 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.
