As described earlier, the basic goal of the research effort summarized in the present document is to develop and implement an adaptive Cohesive/Volumetric Finite Element (CVFE) scheme to simulate efficiently dynamic fracture problems involving the spontaneous initiation, propagation and arrest of one or more cracks. The approach adopted in this project relies on a combination of the adaptive insertion of cohesive elements in the finite element mesh, subcycling, mesh refinement and parallel implementation. Details on these various components are presented in this chapter, together with a summary of the formulation and implementation of the CVFE scheme.
