Abstract : An examination has been carried out of the ability of projectiles of three different geometries to perforate plates of an age hardened aluminum alloy. It was found that flat-ended projectiles perforate the target with greater ease than projectiles with more rounded ends. The results are discussed in terms of the ability of a particular projectile geometry to promote adiabatic shear during penetration and the mode of fracture when projectile breakout occurs. (Author)
