Abstract

The plane-strain fracture toughness, is assumed to represent a size insensitive lower bound value. The materials used for the development of ASTM E 399 were all aluminum and titanium alloys or extra high strength steels. The materials had in common that their fracture micro-mechanism was ductile fracture. The fracture toughness did not show the expected decreasing trend with increasing specimen size, but generally the opposite trend. The specimen thickness was assumed to be the limiting dimension, even though the experimental data indicated that the specimen ligament size controlled the fracture toughness. This lead to several misconceptions regarding the significance of KIC.
