Abstract
In this report we examine the penetration into semi–infinite concrete targets by truncated projectiles. Forrestal’s semi–analytical penetration formula for ogive–nosed projectiles has earlier been seen to give good agreement with experiment. This formula is modified analytically to describe the penetration process for truncated projectiles, both ogive and blunt. The analytical approach is compared to an empirical modification of Forrestal’s formula by Lixin et. al., where a new empirical constant was introduced. The new theory presented here introduces no new empirical constants, and is seen to agree very well with the available experimental data.
