This paper is devoted to the molecular dynamic simulations of the mechanical response of an atomically blunted cavity uncovered and covered by copper atoms, which was observed also experimentally. The cavity is loaded uni-axially in tension mode I. Our question is how the copper atoms influence the ductile-brittle behavior at the crack front of the blunted cavity in comparison with the blunted cavity in pure bcc iron.
