Static and Dynamic Properties of Two Explosive Materials

Abstract

Test rods of Composition B-3 and TNT were cast 43.2 centimeters long and 2.13 centimeters in diameter. The rods were struck axially by spherical steel projectiles, and symmetric stress wave passage was observed by strain gage arrays. Strain pulses were found to attenuate and disperse with travel distance. Both damaged and undamaged rods were examined microscopically using thin-section techniques and were also tested for static compressive and tensile strength. The thin-section technique was able to show grain and crystal damage resulting from impacts. A macroscopic constitutive equation for these materials must take into account their anelastic behavior.
