Analytical response of an earth penetrator
A finite element model and a lumped parameter model of an earth penetrator and its dynamic structural response to a penetration environment are described. The environment is due to a normal impact and penetration into a Dakota sandstone at a velocity of 1800 ft/sec. The problem simulates a reverse ballistic test conducted in September 1976 by AVCO at Falmouth, Mass. The reverse ballistic test consists of propelling a rock target into a stationary penetrator. The penetrator was instrumented with five accelerometers and thirty-six strain gages. The dynamic responses presented predict the accelerations, stresses, and strains that corespond to the instrumented locations. This program was formulated by DNA to investigate state of the art techniques for analyzing the dynamic response of a penetrator.
