TL;DR
This paper reviews how high-resolution digital image correlation helps study how metals deform at a microscopic level.
Contribution
The paper integrates HR-DIC with microstructure analysis, crystal plasticity, and machine learning to better understand strain localization in metals.
Findings
HR-DIC provides sub-micron resolution strain measurements in metallic materials.
Strain localization mechanisms are better understood through integration with crystal plasticity models.
Correlative analysis frameworks enhance the study of heterogeneous deformation processes.
Abstract
Plastic deformation in metallic materials is generally governed by highly localized and intrinsically heterogeneous deformation processes, including crystallographic slip banding, deformation twinning, phase transformation and grain-boundary sliding. These mechanisms operate at the sub-grain scale where they are competing, interacting, and are sometimes incompatible for short-range transmission due to deformation confinement within individual grains. The heterogeneous nature of irreversible deformation at the microstructure scale also applies at the mesoscale, i.e. the scale of the crystalline aggregate. Capturing experimentally the discrete and heterogeneous deformation processes at the microstructure scale is essential to understand elementary deformation processes involved for specific loading conditions, quantifying their intensity to finally achieve a better dialogue with numerical…
