Abstract | The dynamic response of a simply supported underwater laminated pipeline lying on the seabed subjected to underwater explosion shock is studied. A fluid-structure interaction model is given. An approximate approach is introduced to estimate the explosion shock loading. The pipeline is modeled as a simply supported laminated moderately thick cylindrical shell. A modal analysis technique is employed to obtain the dynamic response of the pipeline subjected to underwater explosion shock. From results obtained in this paper, it can be found that the dynamic response of the pipe is local deformation. Compared with the strengths in the circumferential and the longitudinal directions, the strength of the radial direction for the pipe is weaker. Therefore, the response of the radial direction is larger than those of other directions. Some parametric studies including the charge weight, the stand-off distance and the length of the pipe were also considered. |
