Figure 5: Projection in the \(y,z\) plane of segmented microcracks for the heat-treated sample [ACHT01]. Orange ellipse indicates the onset of damage localization, pink ellipse indicates localization along the emerging fault plane. Letters refer to the stress-strain steps in Table 4. Color-coding shows the local fracture aperture at each voxel. See Figure S6 in SI for zip file of high resolution images.
