The characteristics of the plastic enclave at the tip of a crack in a medium subjected to stress are investigated by means of a dislocation model. A model in which dislocations can glide along a plane coplanar with the crack has previously been given by Bilby, CottreU and Swinden (1), and it is the
The basic equations for the representation of crack tip plasticity by an inclined strip yield superdislocation model are derived. The resuRs are put into a form suitable for the analysis of fatigue and other stable crack growth processes. Specialization of the general results for small-scale yieldin
