Linking the microstructure to the mechanical behavior is critical to the design of high-performance components for industry. 3D imaging techniques such as lab/synchrotron X-ray tomography, optical tomography (OCT, OST), and MRI allow researchers to perform
in situ experiments with high spatial (down to the micron scale) and temporal resolution (within seconds). These techniques are particularly suitable for capturing complex and very short-lived phenomena such as localization induced by heterogeneities,
thermal mismatch between constituents, micro-cracking, fatigue behavior, and phase transitions. Digital Volume Correlation (DVC) exploits the natural texture of materials and has recently emerged as a powerful contactless, bulk strain measurement
technique in experimental mechanics, materials science, and biomechanics.
Thermo Scientific™ Amira and Avizo Software are all-in-one image analysis platforms that allow users to compute 3D full-field displacement and strain maps from volume images acquired during the deformation process of an object. The data can be visualized
and analyzed in a sophisticated way to quantify deformation-induced microstructural changes such as strain transfer in multiphase materials, pore growth/coalescence related to fracture, and crack opening displacement (COD).
