Abstract
The shear waves have been taken into consideration to deduce the theoretical model of the scattering of isotropic circular solid cylinders in a fluid medium. The theoretical analysis has been done based on the wave equation and the three classical boundary conditions. The analytical solution of the far-field pattern for this scattering issue has been derived and the pressure in the scattered wave can be given. And the finite element method (FEM) has been used to solve the underwater acoustic scattering problems. Numerical solution of the resulting was discussed in three directions. The following work is to study the scattering problems of collection of cylinders with arbitrary cross-sections and any numbers. The conclusions drawn in this paper could contribute to explore the acoustic propagation characteristics of the two-phase media.
