Abstract Crack tip plasticity is simulated as motion of discrete dislocations. The results of the dislocation model are compared with the predictions of a continuous description of crack tip plasticity in the case of a stationary mode I fatigue crack. It is shown that both the dislocation model and the continuum mechanics lead to the same result at high loading levels but they differ significantly for small stress intensity ranges.
