    Acoustic emission in metals
    (International Institute of Welding, 1976-08-23) Wood, BRA
    For many years man has recognised and given heed to various audible warnings. The creaking of timber in structural applications has long been used as a monitoring device. The familiar "cry of tin" has often been demonstrated to interest students in the study of materials and, on occasions, to impress members of the public. It was not until the early 1950s that any real attempts were made to establish acoustic emission as a field of science rather than a toy or a warning.

    Acoustic emission monitoring of a steam receiver pressurised to failure.
    (Australian Atomic Energy Commission, 1978-04) Brown, KR; Harris, RW; Wood, BRA
    Australian Atomic Energy Commission and the Australian Welding Research Association have conducted acoustic emission monitoring of a large defective pressure vessel during pressurisation to failure. Using acoustic emission source location equipment, it was possible to locate, in real time, areas of high activity. Later, fractographic examination of the failed vessel indicated that failure had initiated at the area of highest activity and this area was identified well before failure occurred.

    Acoustic emission monitoring of a steel bifurcate at Dartmouth Dam
    (Australian Atomic Energy Commission, 1978-02) Harris, RW; Brown, KR; Wood, BRA
    At the invitation of the State Rivers and Water Supply Commission of Victoria, the Australian Atomic Energy Commission conducted acoustic emission monitoring during the proof testing of a large steel bifurcate on the outlet of the Dartmouth Dam under construction on the Mitta Mitta River in Victoria. No indications of defects or local yielding were recorded during pressure testing by the acoustic emission equipment. This result was supported by extensive strain gauging which had been conducted by the Snowy Mountains Engineering Corporation.
