A Taylor-based nonlocal theory of plasticity is proposed to account for the size dependence of plastic deformation at micron and submicron length scales. This theory is intended to link Taylor's model of dislocation hardening to a nonlocal theory of plasticity in which the density of geometrically necessary dislocations is expressed as a nonlocal integral of the strain field. We make application of this theory to void growth, cavitation instabilities and particle-reinforced composites, as well as comparison with experiments on micro-torsion, micro-bending and micro-indentation.
