Abstract:   (367 Views)
Despite the enormous military threats against the country's military facilities, especially the naval industry, correct understanding of the behavior of these structures in efficacy of explosion, analysis and design of this industry has been much importance than ever before. An important class of these threats, is underwater explosion and its effect on various structures, Floating or submerged. In this paper, the researcher first introduces the underwater explosion phenomena and theories that govern the propagation of fluid hydrodynamics, shock waves from the explosion and its interaction with floating and also submerged structures have been investigated. Finally, numerical studies (FEM) of the behavior of a super submarine subject to underwater explosion have been provided by ABAQUS software and some results have been obtained such as: response with different frequencies, the place of radiation boundary in interaction of water and construction, the effect of added mass and hydrodynamic pressure.
Keywords: Finite Element Method, Doubly asymptotic approximation, Submarine, Explosion
