Abstract
Geometrically necessary dislocations (GND) account for the incompatibility of the plastic deformation of single crystals, both in bulk and at the interface. A plethora of measures of GND has been proposed in the literature since 1952: we propose a rationale to choose among these measures, also in relation with recent experimental techiques based on electron backscattering to determine lattice orientation in single crystals.
