Abstract. In World War II non-deforming kinetic energy (KE) projectiles with
velocities beneath 1 000 m/s achieved perforation of the target
by volume deformation and/or plugging. The design of kinetic energy
(KE) projectiles has changed significantly as muzzle velocities have increased,
leading to much higher impact velocities. For projectile velocities above
1 000 m/s the mechanisms of volume deformation and plugging
are replaced by hydrodynamic penetration, where the projectiles are eroding
during the penetration process. This paper provides a brief tutorial
on the penetration of kinetic energy (KE) rounds for projectile
velocities below and above 1 000 m/s. The corresponding penetration
equations are described, after which the paper presents a useful
rule-of-thumb, the experimentally obtained diagram of Hohler and Stilp, and
an analytical equation by Lanz, Jeanquartier and Odermatt. The paper
concludes with a numerical example.
