Dislocations are simplistic objects: they are one-dimensional, their motion is constrained by the crystallography and are surrounded by a stress field that decays with 1/r. However, once dislocations start to interact with themselves or with other microstructures, their collective behavior becomes extremely complex and may give rise to many interesting mechanical properties. This - despite the apparent simplicity of the individual dislocation - is still far from completely being understood.
While today powerful microscopy and simulation methods reveal many important information about systems of dislocations, analysis of such data is still lagging behind. Systematic data mining is still far beyond the possibilities of today's methodologies.
I will present a new approach for characterizing and data mining of dislocation microstructures that works both for experiments and simulations and for different length scales. This approach will then be applied for analyzing in-situ TEM data of dislocation evolution during fracture experiments.
