Abstract : The performance of high yield strength steel plate and weldments, subjected to high levels of dynamic plastic deformation from explosive shock, is an important aspect in the study of materials used in submarine pressure hull construction. This report describes the development of an explosive shock test procedure and its application to study the behaviour of HY80 plate, several shielded metal arc weldments of HY80, and several metal inert gas narrow gap HY80 weldments. An integral part of the submarine materials technology program at Defense Research Establishment Atlantic's Dockyard Laboratory (DREA/DL) is the evaluation of submarine pressure hull weldment response to explosive shock. The ability of the weldment structure to withstand significant plastic deformation prior to the formation and propagation of a crack is an important requirement for modern submarine steels and weldments.
