The Numerical Simulation of the Flow Field of Explosion in Hermitic Cavity and the Response of the Shell Structure

To discuss the flow field of explosion in a hermitic cavity which is charged in center and the dynamic response of the shell structure, a FEA method is used. The overpressure-time curves of the gauges in the structure or on the wall and the deformation of the wall is shown in this paper, and some valuable conclusion is obtained.
