| Abstract: | This paper investigated the axially symmetric compressional wave in a buried infinite elastic rod of circular cross section. The generalized Pochhammer frequency equation was presented, and the corresponding frequency spectral curves in some range of frequency were given. Numerical results show that material parameters have important influences on the spectra character. |

| Keywords: | elastic waveguides dispersion generalized Pochhammer frequency spectra. |
