The ability to quickly estimate the damage that a projectile will do to a structure is highly desired for structures that will be required to resist threats of this nature. There are several formulas for concrete penetration due to projectile impact that are based on empirical data. However, there is a lack of publicly available data for projectile impacts with striking velocities that exceed 1 km/s and have weights greater than a few grams. This research is intended to expand the available data on explosively formed projectile impacts and determine which, if any, of the existing equations can be used or slightly modified to predict penetration depths. In order to determine un-deformed measurements for the explosively formed projectiles, five projectiles were recovered using a soft recovery system. Then, multiple shots were performed using blocks of normal and high strength concrete. The projectiles remained consistent throughout all of the shots --Abstract, page iii
