The effects of penetrator material strength on the terminal ballistic behavior of tungsten alloy segments fired into armor plate was determined by a series of impact experiments. Three different strength tungsten alloys were machined into cylinders with an aspect ratio of 4 and were subsequently impacted into rolled homogeneous armor at 1.5 kms. The depth of penetration and the shape of the penetrator material remaining in the penetration cavity were recorded and compared. Decreasing the penetrator material strength was observed to slightly decrease the length of residual material and the depth of penetration. The diameter of the plastically deformed residual material was observed to increase with decreasing penetrator material strength.
