R curve obtained by a round bar with a circumferential crack and its effectiveness for a fracture toughness test (For a material with medium fracture toughness)
A non-standard circumferentially cracked round bar (CRB) specimen has been examined for replacement of the standard fracture toughness CT specimen since 1981. In the case of a material with low fracture toughness, the CRB specimen can be substituted for the CT specimen. However, when it is applied t...
