Contact induced flaws encountered in glass processing or during its subsequent uses are the main source of strength degradation and damage. These "natural" flaws evolve as microcracks under the influence of external loading by stress concentrations or residual stresses caused by inelastic deformation at localised contacts. Size, density and orientation distribution of these microcracks are dependent on chance. Where their density is high as in impact erosion (sandblasting) microcrack interaction becomes preponderant. In this work the effect of interaction between two crack systems artificially induced by Vickers indentation were studied.
