This research will evaluate prestrain effects on constitutive equations         for plastic flow behavior of materials.  This research investigation            determines the effects of dynamic compressive pre-strain on the                 subsequent plastic flow behavior of metals.  Experimental studies will          be carried out in two fcc metals (6061-T6 aluminum, a fairly rate               insensitive materials, and annealed OFHC copper, a rate sensitive               materials) to understand the micro-structural changes that are                  associated with dynamic compressive pre-strain by means of plate impact         and split Hopkinson bar (SHB) experiments.  The results will be coupled         to a state variable based constitutive model for describing the                 observed plastic flow behaviors in these two materials.
