Fundamental and applied impact investigations have been carried out. The areas of principal effort were hypervelocity impact studies, investigations of ordnance velocity impacts and studies of materials response to planar shock waves. The hypervelocity impact studies produced a large volume of time-resolved data describing impacts into thin sheets and thick plates. Ordnance velocity investigations were applied to immediate Air Force problems involving the ballistic responses of present aircraft components and also provided insights into the ballistic responses of airframe structures and airborne armor. Electrically powered planar impact generators were used to establish the damage thresholds of homogeneous and composite materials when subjected to short- duration shock waves that simulate the environment experienced by reentry vehicles exposed to nuclear explosions. More fundamental studies of materials shock response were also initiated.
