13th International Conference on Fracture June 16–21, 2013, Beijing, China (a) (b) (c) (d) (e) (f) Figure 4: 2D sections at the burnish zone of the steel sheet plane of reconstructed laminography data of damage evolution from a cut-edge at CMODs. (a) The scanned zone (b) material at delivery state; (c) CMOD = 2 mm; (d) CMOD = 3 mm; (e) CMOD = 4 mm; (f) CMOD = 4.5 mm. 4. 3D in-situ observation of damage evolution from a cut-edge Thanks to SRCL it is possible to visualize the voids in three dimensions, as shown in figure 5a-f, where voids are shown in volumes taken around the mid-thickness at different CMODs. Figure 4a shows the as-received material after punching. The fracture and burnish characteristic zones -5-
