Abstract Scope |
Discrete dislocation structures and their evolution are known to control the mechanical properties of metal samples. Specifically, the spatial arrangement of these defect structures plays a fundamental role in this linkage. Although the optimal design of many extreme environment engineering materials requires the careful study and design of these defect systems, the lack of computationally efficient and statistically rigorous descriptors for such defect systems has hindered researchers’ ability to effectively perform these studies. In this presentation, we describe a computational framework for the efficient, rigorous statistical quantification and low-dimensional representation of dislocation structures using the formalism of two-point statistics along with principal component analysis. We also discuss the usefulness of this basic framework for comparing and observing dislocation structures by using the framework to perform an supervised classification of a dislocation structure dataset. |
