Falling weight low velocity ballistic testing and its damage on different type of metals

Abstract

In this research, the damage mechanism applied by the projectile at the ballistic tip on the samples during the ballistic test of the samples consisting of different materials with the same wall thickness as the ballistic test was attempted to determine. Free falling low velocity ballistic test was performed in order to compare stainless steel, brass, copper, low carbon steel materials with the same wall thickness section. A jig consisting of sensitive force readings was set up and its principles were established. This study showed that the projectile tip creates a deformation zone as well as the state of absorbing the impact on the material which are possible to determine by sensitive measurements. Stainless steel and Brass showed better performance than low C steel and Copper due possibly to low work hardening property. K, strength coefficient, showed a significant correlation with the results.
