Geometrically necessary dislocation and size-dependent plasticity

Scripta Materialia, 2003
Abstract There has recently been a strong interest in modeling size-dependent plasticity in metals based on the concept of geometrically necessary dislocations. This article presents a brief summary of our viewpoints on geometrically necessary dislocations and their role in the development of continuum plasticity theories with an intrinsic material ...

Geometrically necessary boundaries, incidental dislocation boundaries and geometrically necessary dislocations

Scripta Materialia, 2003
Abstract The concept of statistically stored and geometrically necessary dislocations is discussed in terms of observed deformation microstructures subdivided by incidental dislocation and geometrically necessary boundaries. This discussion is illustrated by examples of microstructures formed under conditions of homogeneous and nonhomogeneous ...

Assessment of geometrically necessary dislocation levels derived by 3D EBSD

Acta Materialia, 2015
Abstract Existing alternatives for the calculation of geometrically necessary dislocation (GND) densities from orientation fields are discussed. Importantly, we highlight the role of reference frames and consider different sources of error. A well-controlled micro cantilever bending experiment on a copper bicrystal has been analyzed by 3-dimensional ...

A dislocation density based constitutive model for crystal plasticity FEM including geometrically necessary dislocations

Acta Materialia, 2006
A dislocation density based constitutive model for face-centred cubic crystals is introduced and implemented into a crystal plasticity finite element framework. The approach assumes a homogeneous dislocation structure and tracks the dislocation evolution on each slip system.

Crystallographic aspects of geometrically-necessary and statistically-stored dislocation density

Acta Materialia, 1999
Abstract Classical plasticity has reached its limit in describing crystalline material behavior at the micron level and below. Its inability to predict size-dependent effects at this length scale has motivated the use of higher-order gradients to model material behavior at the micron level.
