Title: | Influence of the cross-section geometry of a cylindrical solid submerged in an acoustic medium on wave propagation | Authors: | Pereira, Andreia Tadeu, António António, Julieta |
Issue Date: | 2002 | Citation: | Wave Motion. 36:1 (2002) 23-39 | Abstract: | This paper studies wave propagation in the vicinity of a cylindrical solid formation submerged in an acoustic medium generated by point blast loads placed outside the inclusion. The full 3D solution is obtained first in the frequency domain as a discrete summation of responses for 2D problems defined by a spatial Fourier transform. Each 2D solution is computed using the Boundary Element Method, which makes use of two-and-a-half-dimensional Green's functions. This model is implemented to obtain Fourier spectra responses which make it possible to identify the behavior of both the axisymmetric and non-axisymmetric guided wave modes, when the cross-section of the elastic inclusion changes from circular to smooth oval. | URI: | https://hdl.handle.net/10316/4019 | Rights: | openAccess |
