This research investigates the physical processes involved in the               quasistatic and dynamic fracture of ductile solids, primarily                   structural steels.  Specifically, the effects of inertia, plasticity,           and rate sensitivity will be studied through experiments and analytical         modeling.  The strong effect of plasticity and dynamic loading, and             their interaction, makes such problems particularly important in the            establishment of the necessary design procedures to be used to avoid            failure by fracture.  Analytical models will be developed for crack             initiation and growth in highly ductile solids, and predictions of              these models will be compared with experimental observations.  The              research also involves the development of optical techniques to provide         direct information about the structure of the near-crack tip strain and         displacement fields.
