Synergistic Damage Caused by Multiple Fragment Impact on Closed Systems
AIR FORCE INSTITUTE OF TECHNOLOGY WRIGHT-PATTERSON AFB OH SCHOOL OF ENGINEERING
Pagination or Media Count:
The purpose of this study was to hypothesize the most probable cause for synergistic damage effects sometimes observed when multiple aluminum fragments impact an aluminum box structure. The synergistic damage is characterized by an unexpected increase of pressure within the box causing notable bulging. There are reports of a sudden pressure increase at approximately 8000 ftsec. The study was conducted through literature search and simple engineering approximations.
