- Additional information
- To calculate the geometrically necessary dislocation (GND) density requires computing the curl of a second order tensor. However, unlike for a vector, no clear definition exists. Three different curl definitions are commonly used in the literature, this paper is the first systematic analysis which demonstrates how these different definitions are related and should be used. It also includes a detailed analysis of the GND density under an indent using crystal plasticity finite element simulations and Bragg Coherent X-ray Diffraction Imaging.
