Projectile Impact on Shale.
Abstract
An experimental study was made to obtain data for construction of scaling laws for comminution processes in soft rock. Pulverization of shale and silt targets was done by ballistic impact of hard projectiles ranging from 1/4-inch-diameter steel spheres to a 155-mm ogive-nosed shell. Analysis of the cratering process was achieved with high-speed photography and by examining crater debris. Small-scale laboratory and large-scale in situ tests yield different results which are believed to be due to an increasingly inhomogeneous target in the latter cases. Compaction and fracturing of the target material adjacent to the projectile track appears to be significant.
