A model for dynamic and impact fracture has been recently proposed whereby the fracture event is controlled by adiabatic heating and subsequent melting of the cohesive crack tip craze. The crack initiation resistance is shown to be an inherent function of specimen geometry and impact speed. This theoretical framework allows impact data to be translated from geometry and test speed to another. Dugdale model solutions are also proposed for the Charpy impact test.
