In an effort to simulate dislocation distribution around a Mode I crack, edge dislocations are allowed to be emitted from the crack tip along many possible slip planes containing the crack tip. It turned out that the final distribution depends on the order of emission. So the previous paper dealt with the situation in which the emission process is one at a time, namely after one dislocation is emitted the plastic zone is re-equilibrated before the next dislocation is emitted. In this paper, many dislocations are emitted at the same time when the condition is met, namely, when the slip force exceeds the lattice friction for dislocation motion. It is found that the dislocations are more uniformly distributed than the previous case of sequential emission. The shielding effect for the same number of dislocations emitted is less when the dislocations are distributed along more slip planes. The shape of the plastic zone is different from but the size is comparable with the plastic zone based on von Mises or Tresca criterion. A distinct dislocation-free zone appears when there is a critical stress intensity factor for dislocation emission.
