The geometrically necessary dislocation (GND) and size-dependent plasticity in metals were discussed. The role of GND in the development of continuum plasticity theories with an intrinsic material length scale was presented. It was found that the metallic materials displayed significant size effects when the charcteristic length scale of non-uniform plastic deformation was close to a micron.
