It was noted that an interface exhibited special features in fracture because of its misfit dislocations. Here, ab initio-based interatomic potentials were used to study this problem in a Pt/SiC(111) interface. The entire dynamic process was simulated at the atomistic scale. Micro-cracks and jump points were found in the fracture, which led to interesting results.
