During a programme of transition temperature tests on 6-ft wide plates, strain gauge records, showing the strain field in the plates during fracture, were obtained. This report gives a few typical records and an interpretation of what they mean in terms of the behaviour of the metal when fractured. A possible explanation of how the fracture is self-sustained is also included.
