| Abstract: | The equation of motion in radial direction of a spherical containment vessel has been given with thin-shell approximation. The normally reflected pressure loaded at the inner wall of the vessel is calculated using DYTRAN three-dimensional code. The elastic responses of the vessel are compared when it is loaded by simulated blast load and three kinds of simplified impulsive loads and the influence of loading duration on the response of the vessel is also analyzed.Several issues which should be considered in the design of the vessel are presented. |
