NUMERICAL DISCUSSION OF CREEPING ACOUSTICAL WAVES AROUND CYLINDERS AND SOUND SCATTERING BY ELASTIC CYLINDRICAL SHELLS

摘要

We present the solution for the scattered field corresponding to a plane sound wave incident upon an infinite elastic circular-cylindrical concentric shell, imbedded in a fluid and enclosing another fluid. The results are shown to contain the known special cases of fluid and elastic solid cylinders. Furthermore, limiting expressions for long wavelengths are obtained in special cases.
