Fracture Toughness Data for Brittle Materials



R G. Munro, Stephen W. Freiman, T L. Baker


Fracture toughness data, as represented by the critical stress intensity factor, KIc, and the fracture energy, γ, have been compiled from publicly accessible sources for a wide range of brittle materials with an emphasis on structural ceramics and closely related materials. The results are organized according to the material designation and are presented in annotated tables.
