摘要: The crack growth and expansion characteristics of Fe Ni were studied using the quasi-continuum approach based on embedded atom method (EAM) potential. evaluated in terms atomic stress fields intensity factors. simulation results showed that strength obviously decreased with increasing length. However, at same strain, did not vary upon angle. Moreover, cases orientation I, it was found is more easily broken than Ni, but for II, opposite found.
