  Three-dimensional dislocation networks control the mechanical properties such
as strain hardening of crystals. Due to the complexity of dislocation networks
and their temporal evolution, analysis tools are needed that fully resolve the
dynamic processes of the intrinsic dislocation graph structure. We propose the
use of a graph database for the analysis of three-dimensional dislocation
networks obtained from discrete dislocation dynamics simulations. This makes it
possible to extract (sub-)graphs and their features with relative ease. That
allows for a more holistic view of the evolution of dislocation networks and
for the extraction of homogenized graph features to be incorporated into
continuum formulation. As an illustration, we describe the static and dynamic
analysis of spatio-temporal dislocation graphs as well as graph feature
analysis.
