Abstract

Rapid penetration tests into granular media were performed using spheres and long rods at a wide range of impact velocities up to 300 m/s. The granular media consisted of natural sand or ground fused quartz. Acceleration data were obtained, from which stress was computed. Analysis of results revealed that stress as a function of velocity did not depend on scale or projectile length-to-diameter ratio. Moreover, stress did not display a simple velocity squared dependence. Instead, there were three distinct regimes indicating three different meso-scale material response modes.
