Design of Explosion Blast Containment Vessels for Explosive Ordnance Disposal Units

摘要

This report describes an experimental and analytical investigation of the design and performance of spherical vessels for containment of explosive blast for application by explosive-ordnance disposal teams. During this program a total of eight spherical steel containment vessels were fabricated. The diameters and wall thicknesses investigated were 2.0 ft with 0.5-in. walls, 3.0 ft with 0.75-in. walls, and 4.5 ft with 1.0-in. walls. The vessel ports were approximately one radius in diameter and completely closed by flat steel doors overlaying the ports from the inside. During the course of this program a computer code was developed which calculated the maximum elastic-plastic response and residual plastic strain of spherical, thin-walled vessels in response to an internal, triangular shock wave followed by a static internal pressure. The code in its present form uses measured shock-wave parameters from Pentolite and static pressures which may be calculated for a number of explosives.
