Abstract:

A solution for transient vibration of an elastic shell of revolution surrounded by an acoustic medium is given. The acoustic fluid is modelled through a finite difference scheme based on a mapping from the spheroidal coordinate system. The solution for the shell of revolution is based on a finite difference scheme. The solution is exact to within the order of the finite difference approximations.
