Abstract
This work deals with the calculation of sound radiation from a shell covered with a layer of slightly compressible material and immersed in water. In this case, the assumption of locally reacting material is unrealistic, and a more elaborate model must be used to describe the behavior of the coating layer. This has been achieved by solving the equations of elasticity in cylindrical coordinates, and by use of asymptotic expansions. The layer displacements and stresses are then coupled to the shell displacements and fluid loading on the boundary surfaces. The calculation of shell radiation is made using the normal modes of the in vacuo basic shell, and the asymptotic expansion truncated to the second order. Numerical results are presented showing the influence of layer thickness, damping, and Poisson ratio. [Work supported by D.R.E.T. and C.E.R.D.A.N., Ministère de la Défense.]
