The resonances of finite-length elastic cylinders and elastic spheroids excited by sound scattering

Abstract

The predictions of resonance frequencies for elongated elastic cylinders and spheroids, based on various methods of approach, were discussed in a number of papers in recent years. In the present study, the regions of applicability of the phase matching method for surface waves and of the longitudinal bar wave approximation are examined by comparing the predicted results with the results of T-matrix calculations or with the results of scattering experiments.

Wave propagation in a hollow cylinder due to prescribed velocity at the boundary

“…A large body of references concerns sound scattering by elastic cylinders in the frequency domain. Among these are Stanton (1988), Honarvar and Sinclair (1996), Bao et al (1997), Wang and Ying (2001). Stepanishen and Janus (1990) treat transient radiation and scattering from fluid loaded cylinders.…”

Transient response of a thin cylinder with local material inhomogeneity

“…Stanton (1988), Batard and Quentin (1992), Honarvar and Sinclair (1996), Bao et al (1997), Grinchenko (1999), and Wang and Ying (2001), treat frequency response of thin cylinders. Soldatos and Ye (1994) treat anisotropic laminated cylinders and Lin and Jen (2003) adopt the Chebyshev collocation method for the same problem.…”
