- Abstract
Recently, numerous flexible structures have been employed in various fields of industry. Loading conditions sustained by these flexible structures are often not described well enough for engineering analyses even though these conditions are important. Here, a Submarine Class Seawolf, which is subjected to an explosion, is analyzed. To solve this kind of problem it is mandatory the blast loading and the structural response to be analyzed together due to the interaction between the flexible structure and the dynamic pressure loading. In this paperwork, the dynamic loadings imposed on the exterior sides of the Submarine structure due to the underwater blasts and the resulting dynamic responses were studied. A numerical method of an iterative Fluid-Structure Interaction using Computational Fluid Dynamics and Computational Structural Dynamics was employed to simulate the blast wave propagation outside the structure and to calculate the structure response on it. The rich palette of results shown below are thoroughly investigating the fluid parameters and structure loading/response, all this by using the software Ansys 9.
