Strain gradient plasticity: Theory and experiment
Acta Metallurgica et Materialia, 1994Abstract Dislocation theory is used to invoke a strain gradient theory of rate independent plasticity. Hardening is assumed to result from the accumulation of both randomly stored and geometrically necessary dislocation. The density of the geometrically necessary dislocations scales with the gradient of plastic strain.

On the role of moving elastic–plastic boundaries in strain gradient plasticity
Modelling and Simulation in Materials Science and Engineering, 2006Gradient plasticity theories which are used to describe size effects require nonstandard boundary conditions. We believe that the role of these boundary conditions in combination with a moving elastic–plastic boundary has so far not been well understood. In order to clarify the conditions which are required at such an internal boundary, semi-analytical

Strain gradient plasticity in glassy polymers
2014Plasticity in material is primarily a function of strain. Thus, no length scale enters the constitutive law and no size effect is predicted. However, recent observed plasticity phenomena displayed size dependence. Size dependence can be included in the constitutive law by postulating that yield stress depends upon both strain and strain gradient.
