The LLNL 100-kV electric gun is an experimental device for launching thin flyer plates at velocities as high as 20 km/s to study impact damage and shock-wave physics. The hypervelocity impact studies reported here include a damage study of spalling damage in aluminum, a study of one-dimensional shock-wave attenuation in materials, use of the well-characterized one-dimensional shock waves for equation-of-state measurements in various materials, and use of thin flyer plates at velocities up to 18 km/s to produce reverse ballistic impact on target objects such as rods to measure damage and fragmentation. Our studies include both experimental results and correlation with numerical calculations using a code such as DYNA2D. 2 refs., 9 figs.
