While continuum theory has allowed the determination (at least numerically) of the energy flux into the crack tip process zone for any dynamically growing crack (crack growth velocity comparable to sound velocity), efforts to relate this energy flux to the response of the crack have been only partially successful. While interacting with the material microstructure, dynamically growing cracks result in the release of elastic waves not taken into account in the theory in the absence of their precise knowledge.
