Strain gradient plasticity: Theory and experiment

Acta Metallurgica et Materialia, 1994
Abstract 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.

Strain gradient plasticity in gradient structured metals

Journal of the Mechanics and Physics of Solids, 2020
Abstract 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.

Non-quadratic strain gradient plasticity theory and size effects in constrained shear

Journal of applied mechanics, 2023
A previously proposed strain gradient plasticity theory is extended to incorporate a non-quadratic power law function of the plastic strain gradient in the free energy expression with an exponent of N + 1.

Strain gradients in plasticity [PDF]

Acta Mechanica, 1977
An 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

Stability of strain-gradient plastic materials

Journal of the Mechanics and Physics of Solids, 2011
Abstract A formulation of Fleck and Willis (2009a,b) for strain-gradient plasticity has been adapted to provide possible descriptions for materials that initially strain-harden but eventually soften. In the absence of gradient terms, such material is unstable for any wavelength and subject to localization in the softening regime.
