Abstract

We review recent progress in the development of spacetime discontinuous Galerkin (SDG) finite element methods for modeling dynamic fracture with cohesive damage models. After reviewing the formulation and implementation of an adaptive SDG cohesive model, we describe new investigations of crack-tip kinetics and singular structure in the near-tip velocity field. We discuss prospects for tracking solution-dependent crack paths and for nucleating cohesive interfaces using an extended set of spacetime meshing operations.
