The early work of Griffith and others on crack propagation has in recent years been extended and systematized to form the science of Fracture Mechanics. In dealing with stationary cracks its principal theoretical tools are the stress intensity factor which characterizes the elastic field near a crack tip and the energy release rate associated with the extension of a crack. The behaviour of fast-moving cracks presents some intriguing theoretical problems which are only beginning to be solved.
