Careful studies of cleavage fracture surfaces show that parts of the surface consist of plastically formed ridges, presumably traces of plastically collapsed ligaments. These ligaments are assumed to be formed between the cleavage fractured areas. The collapse process of these ligaments is numerically examined. A finite element method and an asymptotic analysis are employed. The results shows that relatively large amounts of energy are consumed in this process and that the energy consumption is increasing rapidly with increasing crack tip speed. The implications for slow stable crack tip speeds at dynamic fracture are discussed.
