On the current understanding of strain gradient plasticity
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2004Some current strain gradient plasticity theories of non-homogeneous deformation and size effects are discussed critically, in particular with respect to the question how the density of geometrically necessary dislocations contributes to the flow stress.

Strain gradient plasticity in gradient structured metals
Journal of the Mechanics and Physics of Solids, 2020Abstract Structural gradients in metallic materials can give rise to substantial extra strengths compared to their non-gradient counterparts. This strengthening effect originates from the plastic strain gradients arising in plastically deformed gradient structures.

A strain gradient theory of plasticity
International Journal of Solids and Structures, 1970Abstract A theory which includes first and second strain gradients is proposed as a model for plastic deformations. Heuristic arguments for including the gradients are also given. The main goal is to develop a logical framework in which behavior on a small scale can interact with the response on a larger one.

Strain gradients in plasticity
Acta Mechanica, 1977An analytical model of a plastically deforming solid is assumed to be a material where the second spatial gradients of strain are included in the constitutive equations. These constitutive equations are combined, in a one dimensional shearing problem, with the second law of thermodynamics and condition of thermodynamic stability. The results are that a

Formulations of Strain Gradient Plasticity
2011In the literature, different proposals for a strain gradient plasticity theory exist. So there is still a debate on the formulation of strain gradient plasticity models used for predicting size effects in the plastic deformation of materials. Three such formulations from the literature are discussed in this work.
