Abstract
The energy release rate G is a measure of the elastic energy causing crack propagation whereas the fracture heat Q indicates the amount of energy dissipated in the fracture zone. As long as any change in structure and energy losts by elastic waves can be neglected, the fracture heat represents the energy consumption of the crack and should be equivalent with G. If this can be proven one could use Q- measurements as an alternative method for investigating running cracks and dynamic fracture criteria, which in some cases may be a more appropriate measurement of the dynamic energy release rate G dyn or the dynamic stress intensity factor K dyn .
