In this paper the measurement of fracture toughness K1, by single cylindrical tensile specimen with ring-shaped crack is described. The specimen does not satisfy the size requirement for effective plane strain fracture toughness K,,. The principle assumed here is that the curve, normalizing the load
Abstmc(-In this paper the calculating method of the condition value I& of the plane-strain fracture toughness for cylindrical specimen with ring-shaped crack is studied according to the standard test method for plane-strain fracture toughness of metallic materials. The corresponding condition load P
