Influence of Hardness on Perforation Velocity in Steel Armour Plates

摘要

In an earlier investigation, the influence of hardness on tempered steel armour plates of 20 mm thickness, impacted by 20 mm diameter steel ogive-shaped projectile at normal, was studied. Additional data is investigated with relation to the perforation velocity of the plates. It is observed that the plate perforation velocity and the plate plugging velocity decrease with increasing plate hardness.
