This report describes the approach and methods used in the analysis of a containment vessel that is being designed for use at the Dual-Axis Radiographic Hydrodynamic Test Facility (DARHT). The vessel will be subjected to transient pressure loads during explosive tests conducted at the facility and is required to contain all of the products of these tests. Computational simulations of the structural response of the vessel have been made using a combination of two numerical techniques: the transient pressure histories acting on the inner surfaces of the vessel were computed using an Eulerian hydrodynamics code, and the vessel`s structural response to these pressures was analyzed using an explicit finite element code. The methods and approximations involved in combining these two numerical analysis tools will be discussed, and the stresses produced in the vessel and important measures of the dynamic response will be presented
