A test program was conducted to obtain a complete set of penetration data for steel spheres impacting Aluminum Targets. The Striking speed varied in the range of 100-1800 meterssecond for two sphere diameters 0.635 and 1.191 cm., three impact angles 0, 45 and 60 degrees and three plate thicknesses 0. 635, 1.270 and 5.08 or 7.62 cm.. Exit velocity was obtained for the ricochet and the complete penetration regions and the embedment region was determined. Various parameters are tabulated such as crater size, hole size and depth of penetration.
