Containment Structures Versus Suppressive Structures
ARMY BALLISTIC RESEARCH LAB ABERDEEN PROVING GROUND MD
Pagination or Media Count:
As part of a study of the suppressive structure concept, analyses of the large deflection, elastoplastic response of two configurations a hemispherical shell and a cylindrical shell with closed ends subjected to internal blast were performed. These blast and fragment containment structures may be regarded as limiting cases of suppressive structures and the results obtained are believed to constitute useful baseline data for evaluating efficiency of suppressive structure designs. The results indicate that these simple structures can provide total containment of fragments and blast for significantly less weight and cost than a corresponding vented suppressive structure. Suggestions regarding more practical containmentsuppressive structural configurations are included.
