Fig.4. Evolutions of the system with the interaction between the dislocation loop and micro-crack with d=4.5 nm, k=0.05 and R=1.5 nm(a) formation of 1/2[] dislocation segment after the conjugate gradient method relaxation (b~e) molecular dynamics simulation results at 300 K under 0 Pa pressure with time up to 1.8×10-11 s, 3×10-11 s, 3.09×10-11 and 3.12×10-11 s, respectively (The movements of dislocation loop and 1/2[] dislocation segment along their Burgers vectors are shown in Figs.4b and c, respectively. The interactions between them are shown in Figs.4d and e)
