Abstract

One of the PASSIVE DEFENSe topics is the retrofitting of structures under explosive effects. The water medium has more effect on submarine and marine structures subjected to explosion. Having large marine border in our country, it is necessary to study these phenomena. Regarding the geometrical shape of submarine and marine infrastructure, there are lots of studies concerning the flat and cylindrical plates. In this paper the effect of charge weight and standoff on plate deformation have been studied using ABAQUS / Explicit software and the results have been accurately confirmed when compared with available reported experimental results and relationships. Simulation methods, coefficients and parameters used in this paper can be used in the case of study and simulation of structure response subjected to underwater explosion load. By VERIFICATION of conducted simulation, the initial design of cylindrical TEST CHAMBER in two states without stiffener and with stiffener under the effect of underwater explosion load has been assessed. By design of chamber using stiffener, the weight of chamber and effective cost are reduced considerably.
