A series of 14 impact experiments has been performed in which solid and layered targets nominally 3 x 3-in. by 0.5-in. thick have been impacted by 0.5-in. steel cubes in a flat-faced orientation. The number of target layers varied from one to five. The areal density of the targets ranged from 3.6 to 11. 1 gmsq cm. Three experiments were performed at an impact velocity ranging from 2000 to 2500 ftsec and eleven experiments were performed at a velocity of approximately 3100 ftsec. Target perforation did not occur in six of the higher velocity experiments. For these experiments, the number of target layers was either one or two. Target perforation occurred in five of the higher velocity experiments the number of target layers was either three, four, or five for these experiments. Target failure consisted of one or more of the following types cratering, shear bands, shear plugging, fracture, plate bending, petalling, and fiber breaking.
