چکیده مقاله:
Underwater explosion (UNDEX) is one of the most complex physical problems. In addition to its attractive theoretical aspects, today’s it became to a vital matter in war and terrorism events. It has beenthe subject of many scientific researchers for many years. Investigation of submerged structures subjected to underwater explosion, is one of the important researches. In the present study the dynamic response of two submerged and different stiffened steel structures subjected to underwater explosion is presented. The structures are composed of ring-stiffened cylinders. The structures and surrounding water are modeled byshell and acoustic finite elements respectively. The system was analyzed by an acoustic pressure shockwave resulting from an underwater explosion (UNDEX). The incident wave is the shock wave produced by the UNDEX charge. The deduced results such as displacement and strain at some important nodes of structures are presented and compared
