Mj. Berliner et R. Solecki, WAVE-PROPAGATION IN FLUID-LOADED, TRANSVERSELY ISOTROPIC CYLINDERS .2. NUMERICAL RESULTS, The Journal of the Acoustical Society of America, 99(4), 1996, pp. 1848-1853
The frequency equation of a coupled system consisting of an infinitely
long, fluid-loaded, homogeneous, transversely isotropic cylinder was
derived in Part I [J. Acoust. Sec. Am. 99, 1841-1847 (1996)]. In this
paper, Part n, the frequency spectra for the n=1 nonaxisymmetric modes
of wave propagation are presented for hollow cylinders, fluid-filled
cylinders, and cylinders that are fluid filled and immersed in fluid.
These frequency spectra consist of the first three branches correspond
ing to the flexural mode, the longitudinal mode, and the circumferenti
al mode. Since propagation modes are of primary interest, branches ext
ending into the imaginary and complex wave-number domain are not inclu
ded in this study. Numerical results for an isotropic (linearly elasti
c) rubber cylinder are compared to the results for a highly anisotropi
c, fiber-reinforced cylinder. The material properties of the rubber cy
linder are identical to the properties of the matrix material of the f
iber-reinforced cylinder. It is shown that the characteristics of wave
propagation in the fiber-reinforced cylinder, with and without fluid
loading, are markedly different from the characteristics of wave propa
gation in the isotropic cylinder. (C) 1996 Acoustical Society of Ameri
