The figure shows a centrosymmetry analysis of the dislocation and defect structure in the metallic nanocomposite as obtained from molecular dynamics simulations, emphasizing the slipped regions during initial plasticity. The black region depicts the location of the hard platelet embedded in a soft matrix.
