Abstract
From the Introduction: Historically, laboratory tests to select materials to avoid brittle fracture have centered around the use of small notched specimens subjected to impact loading. A quantity called transition temperature (T. T.) is measured. In concept, the transition temperature approach states that below the T. T. the energy absorbed by a specimen in fracture is small, and fracture may occur at normal stresses in a structure below the yield strength (frangible), whereas above the T. T. the energy absorbed by a specimen in fracture is large, and fracture will not occur until the nominal stress in a structure exceeds the yield strength. While simple in concept, this approach has been questioned on the basis of fracture experience with high strength steels that exhibit low values of upper shelf energies. In addition, considerable confusion has surrounded the several vaguely related operational definitions of T. T.
