Abstract Scope The basic flaw-strength relationship based on linear elastic fracture mechanics has been proven experimentally for glass. The flaw depth controls the strength in the expected inverse square root fashion. When glass is damaged through mechanical contact, the subsurface arrangement of flaws can be less than ideal. One special, but common, case is where lateral cracks form beneath radial or Palmquist cracks, effectively shielding these cracks from joining up to form a well-organized elliptical crack. This work explores how those complicated fractographic features affect the retained strength of the flaw.
