Dislocation modelling of stage I fatigue crack growth

A simulation of the dynamics of generation, motion and interaction of dislocations in the stress field ahead of a mode II crack under a cyclic loading is presented. The cyclic plastic displacement at the crack tip allows the growth rate to be determined. Crack growth rate curves show an inherent thr...
