Fourteen hollow concrete cylindrical hulls ranging in length from 8 to 128 inches and having an outside diameter of 16 inches and a wall thickness of 2 inches were subjected to hydrostatic loading to determine the effect of cylinder length-to-outside-diameter ratio LD o on the implosion pressure and strain behavior, and the distance from the edge of the cylinder in which radial displacement was influenced by the end closure. Hemispherical end closures were joined to the cylinders with epoxy, silicone rubber, or steel dowel pins and epoxy. The uniaxial compressive strength of the concrete averaged approximately 9,500 psi.
