There has recently been a strong interest in modeling size-dependent plasticity in metals based on the concept of geometrically necessary dislocations. A brief summary was presented of the authors’ viewpoints on geometrically necessary dislocations and their role in the development of continuum plasticity theories with an intrinsic material length scale.
