Abstract:

Structures designed as venting enclosures have been proposed to contain and suppress the explosions resulting from the accidental detonation of explosives during their manufacture, handling, and storage. These structures must provide total containment of fragments, partial suppression of the shock wave, and a controlled release of the internal quasi-static pressure. Because of the relatively low frequency of accidental detonations, the most cost effective approach to the design of such structures appears to be one utilizing inexpensive and easily erectable structures which can be replaced after an explosion. This report provides 1 Development of a structural response model for suppressive shield structures, along with results from sample computations 2 Results of hydrocode calculations for shock interactions with suppressive shield-type panels which provide time-dependent blast loadingtransmission functions and 3 Computed results for time-dependent internal pressure loads produced by burning propellantspyrotechnics inside a vented enclosure.
