Materials diagnostics

X-ray computed tomography (CT) plays a crucial role in materials science as it enables the non-destructive investigation of the three-dimensional morphology of materials, such as fibers, ceramics, and composites. When combined with in-situ mechanical testing, CT improves our ability to observe how deformation mechanisms occur and how damage accumulates in samples under mechanical stress. Furthermore, the microstructural images produced by CT of actual samples under stress can be used as inputs for numerical modeling.
