The traditional fully stressed method performs satisfactorily for stress-limited structural design. When this method is extended to include displacement limitations in addition to stress constraints, it is known as the Fully Utilized Design (FUD). Ty

Minimizing the weight of structural components of the Space Station launched onto orbit in a space shuttle can save cost, reduce the number of space shuttle missions and facilitate on-orbit fabrication. Traditional manual design of such components, a

Weight minimization is an important requirement in the design of components of the Space Station, since it can directly save launch cost, reduce the number of space shuttle missions, and facilitate on orbit assembly and fabrication. Preliminary optim

An algorithm similar to the optimality criteria approach used in structural optimization is presented for identifying stiffnesses of structural members by using vibration test data. A set of equivalent static inertia forces are obtained from the vibr
