چکیده
In the present research, mass optimization of grid stiffened composite shell under external hydrostatic pressure has been investigated. At first, mass function as an objective function has been presented. Subsequently, buckling analysis of grid stiffened composite shell has been done to determine constraint function of optimization. For optimization process, some parameters can be used to increase mechanical performance of grid stiffened composite shell. The quantity of stiffeners, cross section area and the angle of stiffener are the variables which have been used to minimize mass by considering buckling criteria. Genetic algorithm has been used to reach optimal design of the grid stiffened composite shell. The results show that optimization problem has been converged in the 10 generations. Finally, the best model which has the minimum mass and satisfied buckling pressure has been presented.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
