Abstrakt: Deals with a study which determined the fracture toughness of small volumes of brittle materials through the pyramidal indenters to initiate radial cracks. Definition of the pop-in phenomenon in indented brittle materials; Determination of extra penetration h[subx]; Penetration by indenter of a sub-surface void of brittle materials.
