Damage Evaluation and Debris Plume Analysis for Spaced Target Under High Velocity Impact Conditions

RAJNISH GOYAL, V. VENKATARAMAN

Abstract


High velocity impact experiments have been carried out with tungsten alloy projectiles against multiple-plate spaced target configuration using a two stage gas gun facility over a wide range of velocity. The damage on the target layers have been characterized with help of high speed imaging, shock measurements and debris plume analysis. The entry damage diameters have been measured for the target plates and the damage region is defined using damage cone angles. It has been observed that the damage cone angle increases with increase in impact velocity, in general. The entry damage diameter on the first layer remains almost same and that for the second layer increases within a band with the increase in impact velocity for the range of velocity under consideration.
