Abstract
The objective of this investigation is to study the effect of projectile (a ball) hardness and density in relation to target material hardness, on the volume of the crater formed by the impact of the target material with the ball over a range of velocities (20-200 m/s). For this purpose, copper (HV48) and steel (HV551) targets, representing the extreme with respect to hardness, have been impacted by a variety of balls having a wide range of hardness and density. The results indicate that the crater volume is determined by the kinetic energy of the ball irrespective of its density and hardness. However, if the hardness of the ball is less than 1.5 times the target material hardness, the ball also undergoes plastic deformation during impact and, a result, the crater volume now becomes a function of the ball hardness also.
