Acoustic wave scattering from transversely isotropic cylinders

摘要: Mathematical expressions are derived for the far‐field backscattering amplitude spectrum resulting from oblique insonification of an infinite, transversely isotropic elastic cylinder by a plane acoustic wave. The normal‐mode solution is based on decoupling scalar potential representing horizontally polarized shear wave those compressional and vertically waves. degenerates to well‐known simple model cylinders in case very weak anisotropy. used study influence each element stiffness matrix various resonant modes vibration. Perturbations elements c33 c44, which characterize along axis, significantly affect frequencies corresponding axially guided c11 c12, material transverse plane, predominantly Rayleigh Whispering Gallery resonance frequencies. c13 all three ty...
