Finite element solution of the interaction of a plane acoustic blast wave and a cylindric structure

The finite element method is used to study the structural response of a submarine to an acoustic blast wave. Encounter geometry is restricted to the case of a plane wave front parallel to the axis of a right-circular cylindric structure. It is shown that the blast wave propagation may be studied separately from the structural response. For the case considered this separation allows a two-dimensional formulation of the propagation problem while retaining a three-dimensional structural model. Propagation results are found to agree well with analytic results obtained by others.
