Abstract

Crack tip atom-string model is devised to study non-linear features of dislocation emission processes under mode II loads. Dynamic analysis shows that the atom motion at the crack tip changes from periodic to chaotic as the stress intensity factor increases. Study on the dislocation emission band reveals the phenomenon of cloud-like drifting of the dislocation core ahead of the crack tip.
