Semi-Infinite Target Design Effects on Terminal Ballistics Performance - Influence of Plate Spacing on Penetrator Energy Partitioning

Abstract

The difference in terminal ballistic performance of four semi-infinite target designs fabricated with different amounts of plate spacing was investigated. Three of the target designs were made from 25-mm-thick steel plates stacked together with either 0, 1.5, or 3.0-mm space between each plate. The fourth target design was a single, monolithic block of steel. Each target was impacted with a kinetic-energy penetrator made from tungsten-sintered alloy at an approximate speed of 1600 m/s. Plate spacing was found to result in increased penetration depth. Several energy sink sources are considered to explain the fundamental mechanisms associated with the observed results.
