Abstract :
This study presents a comparison of extended finite elements (XFEM), cohesive zone model (CZM) and the peridynamic theory (PD). By comparisons against two experimental benchmark studies, the capability of these techniques to predict dynamic fracture is demonstrated through both qualitative and quantitative observations.
