摘要: The multilevel approach to minimum weight structural design is extended wing box structures with fiber-composite stiffened-panel components. Strength, deflection, and panel buckling constraints are treated at the system level equivalent-thickness-type variables. Local guarded against component level, employing detailed dimensions as A key feature of method selection change in stiffness objective function be minimized. Numerical results given for sandwich hat-stiffened panels.
