(a) Photos of the observed cracks at the upper part of the free surface (X = 62 mm). (b) The observed cracks mapped onto X-Y plane, where the free surface is on the right-hand side (X = 62 mm).. Note that the cracks on SR2 sample are hairline thin. (c) Photos of the observed cracks on the Z = 80 mm surface.
