Analytical and Experimental Studies on Penetration into Geological Targets

This paper summarizes some recent analytical and experimental work on penetration into geological targets. Results from several elastic-plastic type theoretical models which predict forces on penetrators for normal impact into dry porous rock, concrete, and sea ice targets are presented and compared...

Description
Summary:This paper summarizes some recent analytical and experimental work on penetration into geological targets. Results from several elastic-plastic type theoretical models which predict forces on penetrators for normal impact into dry porous rock, concrete, and sea ice targets are presented and compared with measurements from field tests. Rigid-body acceleration data from newly developed laboratory scale experiments for impact velocities between 0.2 and 1.2 km/s are also presented. This article is from 'The Interaction of Non-Nuclear Munitions with Structures: Symposium Proceedings Held at U.S. Air Force Academy, Colorado on May 10-13, 1983. Part 1,' AD-A132 115, p23-26. Prepared in cooperation with Ktech Corp., Albuquerque, NM.
