A numerical analysis of some spherically symmetric containment vessel problems is accomplished using the one-dimensional hydrodynamics code SIN. The typical problem involves a spherical steel vessel containing a detonating spherical charge of PBX-9404 at its center, with a mitigator (air or vermiculite) surrounding the charge. Two different vessels are considered - one having 17.6-cm inner radius and 0.635-cm-thick shell and the other having an 88.9-cm inner radius and a 6.35-cm-thick shell. Three different charge masses are used: 15.82 g, 8.17 kg, and 27.24 kg. In each configuration considered, the displacement of the shells and the pressure in the air at the inner wall are obtained as a function of time. The results agree well with experimental data. A simple theoretical model is also considered and gives solutions in reasonable agreement with the numerical results.
