Title: | Dynamic analysis of submerged fluid-filled pipelines subjected to a point pressure load | Authors: | Godinho, L. Tadeu, A. Branco, F. J. G. |
Issue Date: | 2004 | Citation: | Journal of Sound and Vibration. 271:1-2 (2004) 257-277 | Abstract: | This paper analyses the wave scattering generated by point pressure loads in the vicinity of infinite fluid-filled circular pipelines submerged in a homogeneous fluid medium. The pipeline has a constant cross-section and is modelled as a homogeneous elastic material. The three-dimensional (3-D) response is formulated in the frequency domain, and is obtained as a discrete summation of the 2-D solutions found for different axial wavenumbers. Time solutions are computed by means of inverse Fourier transforms. Complex frequencies are used to avoid aliasing phenomena. | URI: | https://hdl.handle.net/10316/3993 | DOI: | 10.1016/S0022-460X(03)00752-1 | Rights: | openAccess |
