Abstract

The ductile fracture process of iron with the various grain diameters under the tensile strain was examined at the atomic scale by means of molecular dynamics (MD) simulation. The results of the MD simulation quantitatively revealed that the energy for fracture decreased and the strain increased with the increase of the grain diameter. Additionally, the generation of dislocation was observed before the fracture in all of the crystal with the various grain diameters. Furthermore, the void was generated from the grain boundary and the fracture occurred along the grain boundary.
