Dislocation cartography: Representations and unsupervised classification of dislocation networks with unique fingerprints

Detecting structure in data is the first step to arrive at meaningful representations for systems. This is particularly challenging for evolving dislocation networks evolving as a consequence of plastic deformation of crystalline materials. Our study employs Isomap, a manifold learning technique, to...

description Detecting structure in data is the first step to arrive at meaningful representations for systems. This is particularly challenging for evolving dislocation networks evolving as a consequence of plastic deformation of crystalline materials. Our study employs Isomap, a manifold learning technique, to show the intrinsic structure of high-dimensional dislocation density field data of dislocation structures resulting from different compression axes. Our maps provide a systematic framework for quantitatively comparing dislocation structures and offer unique fingerprints based on dislocation density fields. It represents a novel, unbiased approach that contributes to the quantitative classification of dislocation structures, which can be systematically extended using different representations of dislocation systems.
