heal.abstract	Dynamic crack propagation in thin, edge-notched polystyrene specimens was studied by the method of dynamic caustics. During crack propagation, an intensive zone of crazing surrounds and precedes the propagating crack. Therefore, an active zone ahead of the crack tip is developed. This active zone is related to the velocity of crack propagation and the strain rate of loading. The velocity of the crack and the stress intensity factor, KI, or the energy release rate, GI, were strongly influenced by the development of the active zone at the crack tip. © 1992 Chapman & Hall.	en
