Abstract
A series of terminal ballistic tests with 7.62 mm APM2 projectiles was performed in order to correlate the resistance to penetration of differently-treated Ti6A14V plates with their dynamic properties. These properties were determined with a Split Hopkinson Bar (SHB) which resulted in the well known features of adiabatic shear for this alloy. The ballistic efficiency of the target plates correlate well with the area under the dynamic stress-strain curve (energy) up to the point of instability which marks the onset of adiabatic shear. We also discuss other features of the interaction between the AP rounds and plates, in particular the transition from plug formation to the ductile-hole mode of penetration and the role of copper sleeve surrounding the hard steel core (of the projectile) on the penetration process.
