Size Dependence of Dislocation-Mediated Plasticity in Ni Single Crystals: Molecular Dynamics Simulations

Figure 3

Octahedral shear stress distribution at initial yielding of 10 nm ⟨134⟩-oriented nanopillar. The stress value of each point is obtained by averaging the Virial stresses of atoms in a sphere (centered at this point and with a radius of the cut-off distance used in the EAM potentials). The length unit is Angstrom, and the stress unit is MPa.
