  A variational discrete element method is applied to simulate quasi-static
crack propagation. Cracks are considered to propagate between the mesh cells
through the mesh facets. The elastic behaviour is parametrized by the
continuous mechanical parameters (Young modulus and Poisson ratio). A discrete
energetic cracking criterion coupled to a discrete kinking criterion guide the
cracking process. Two-dimensional numerical examples are presented to
illustrate the robustness and versatility of the method.
