IMPACT FAILURE OF PRESSURE VESSELS -- PART 2. 11 OCTOBER 1963

Abstract

The objective of this program is to provide a means for predicting the conditions under which a pressure vessel will fail due to hypervelocity impact. A major segment of the experimental portion of the program has been accomplished. The data show that a preimpact stress field does not affect hypervelocity cratering or penetration, but the conditions for catastrophic fracture depend on both the stress field and the hole size. A correlating factor between the preimpact stress and the hole has been established. Systematic test series of shielded structural arrangements have been performed to investigate projectile dispersion, cratering characteristics, impact damage, and failure modes. Interrelationships between projectile geometry, specimen size, material, and structural damage have been observed. In addition, tests have shown that the limiting conditions for catastrophic fracture of gas- and liquid-filled pressure vessels differ from each other; further investigations are needed, especially to determine failure conditions for liquid-filled vessels.
