Abstract
In this study, the numerical simulation of fatigue crack propagation in plane strain state was conducted using the discrete dislocations method and the effect of pile-ups of edge dislocations in this method is discussed. In the numerical simulation, the nucleation and the motion of dislocations are constrained by the pile-ups of dislocations which are nucleated in the past cycles, thus, the crack propagation rate after the second cycle is decreased compared with the first cycle.
