High-energy mesoscale strips observed in two-dimensional atomistic modeling of plastic deformation of nano-polycrystal

Plastic deformation of two-dimensional polycrystal with nano-size grains is investigated by means of molecular dynamics simulations. High-energy mesoscale strips are revealed and their properties are studied. It is demonstrated that the atoms within the mesoscale strips have higher potential energy and smaller mean interatomic distance than the rest of the atoms with ideal coordination number.
