The geometrically necessary dislocation (GND) is relevant to the deformation mechanism of crystalline structured materials at the micro scale. The density and distribution of GNDs are associated with the strain gradient, and consequently, the size effect. Recently, we introduced GNDs in single-crystalline tungsten using a sharp wedge tip and experimentally determined the GND density distribution via transmission Kikuchi diffraction (TKD) and Nye-Kröner tensor. By applying a line load along a specific loading direction, the in-plane deformation condition was achieved and only one slip plane family of edge dislocation was activated. In this study, we extended this experimental method to different constraint conditions, i.e., by changing the tip shape and the volume of the material for indentation, and characterized the individual GND density distribution quantitatively. Depending on the constraint condition, differences in the GND distributions were observed. Only certain slip systems were activated, which was also confirmed numerically.
