(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-
