Investigation of Oblique Shocks and Edge Effects for Underground Targets. Volume 2. Edge Effects
Abstract
This report summarizes results of a four-month test and analysis program to establish maximum breach distances for explosives placed at several positions about the corner of a buried concrete structure. The objective of the program was to generate test data showing explosive charge stand-off distances at which buried concrete structures will be breached for charges placed on the corner diagonal, the corner shear line, and the mid-span of the wall. Composition C-4 explosive charges were detonated against high strength concrete cubicles with walls 4 and 8-inches thick. One-third scaling was used for all tests, and quartz pressure transducers recorded force and impulse data on the target wall and in the free soil. Results of the study showed that difficulty of breaching the walls of the buried concrete targets increased dramatically as the explosive charge is moved from mid-span to shear line to diagonal positions. Recommendations are to initiate use of these findings in target vulnerability analysis of high explosive munitions encountering underground concrete structures.
