5.1 The fracture toughness determined by this test method characterizes the resistance of a material to fracture by a slowly advancing steady-state crack (see 3.2.5) in a neutral environment under severe tensile constraint. The state of stress near the crack front approaches plane strain, and the crack-tip plastic region is small compared with the crack size and specimen dimensions in the constraint direction. A KIv or 5.1.1 The KIv, 5.1.2 Plane-strain fracture toughness testing is unusual in that there can be no advance assurance that a valid 5.2 This test method can serve the following purposes: 5.2.1 To establish the effects of metallurgical variables such as composition or heat treatment, or of fabricating operations such as welding or forming, on the fracture toughness of new or existing materials. 5.2.2 For specifications of acceptance
and manufacturing quality control, but only when there is a sound
basis for specification of minimum KIv,
5.2.3 To provide high spatial resolution
in measuring plane strain fracture toughness variations in parent
pieces of material Note 2: The high spatial resolution is possible because of the
small allowable specimen size criterion, B ≥1.25
