Abstract Hierarchical guidance is developed for three-dimensional (3D) nanoscale X-ray imaging, enabling identification, refinement, and tracking of regions of interest (ROIs) within specimens considerably exceeding the field of view. This opens up n

Microscopic digital volume correlation (DVC) and finite element precoalescence strain evaluations are compared for two nodular cast iron specimens. Displacement fields from \textit{in-situ} 3D synchrotron laminography images are obtained by DVC. Subs

Although digital volume correlation (DVC) seems to be a simple extension of digital image correlation to 3D situations, new challenges arise. The first problem is that the actual microstructure of the material can hardly be varied overall to improve
