The main body of work in this area is concerned with the control of time-dependent displacements and stresses, and assumes linear elastic conditions, namely linear elastic material behavior and small defor- tion. See, e. g. , [1]–[3], the collections of papers [4, 5], and references therein. On the other hand, in the present paper we consider the static optimal control of a structure made of a nonlinear elastic material and und- going large deformation. An important application is the suppression of static or quasi-static elastic deformation in flexible space structures such as parts of satellites by the use of control loads [6]. Solar rad- tion and radiation from other sources induce a temperature field in the structure, which in turn generates an elastic displacement field. The displacements must usually satisfy certain limitations dictated by the allowed working conditions of various orientation-sensitive instruments and antennas in the space vehicle. For example, a parabolic reflector may cease to be effective when undergoing large deflection. The elastic deformation can be reduced by use of control loads, which may be imp- mented via mechanically-based actuators or more modern piezoelectric devices. When the structure under consideration is made of a rubb- like material and is undergoing large deformation, nonlinear material and geometric effects must be taken into account in the analysis.

Available in PDF, EPUB and Kindle. Book excerpt: Flying Camelot brings us back to the post-Vietnam era, when the US Air Force launched two new, state-of-the art fighter aircraft: the F-15 Eagle and the F-16 Fighting Falcon. It was an era when debates about aircraft superiority went public—and these were not uncontested discussions. Michael W. Hankins delves deep into the fighter pilot culture that gave rise to both designs, showing how a small but vocal group of pilots, engineers, and analysts in the Department of Defense weaponized their own culture to affect technological development and larger political change. The design and advancement of the F-15 and F-16 reflected this group's nostalgic desire to recapture the best of World War I air combat. Known as the "Fighter Mafia," and later growing into the media savvy political powerhouse "Reform Movement," it believed that American weapons systems were too complicated and expensive, and thus vulnerable. The group's leader was Colonel John Boyd, a contentious former fighter pilot heralded as a messianic figure by many in its ranks. He and his group advocated for a shift in focus from the multi-role interceptors the Air Force had designed in the early Cold War towards specialized air-to-air combat dogfighters. Their influence stretched beyond design and into larger politicized debates about US national security, debates that still resonate today. A biography of fighter pilot culture and the nostalgia that drove decision-making, Flying Camelot deftly engages both popular culture and archives to animate the movement that shook the foundations of the Pentagon and Congress.

Available in PDF, EPUB and Kindle. Book excerpt: Thin shells are very popular structures in many different branches of engineering. There are the domes, water and cooling towers, the contain ments in civil engineering, the pressure vessels and pipes in mechanical and nuclear engineering, storage tanks and platform components in marine and offshore engineering, the car bodies in the automobile industry, planes, rockets and space structures in aeronautical engineering, to mention only a few examples of the broad spectrum of application. In addition there is the large applied mechanics group involved in all the computational and experimental work in this area. Thin shells are in a way optimal structures. They play the role of·the "primadonnas" among all kinds of structures. Their performance can be extraordinary, but they can also be very sensitive. The susceptibility to buckling is a typical example. David Bushnell says in his recent review paper entitled "Buckling of Shells - Pitfall for DeSigners": "To the layman buckling is a mysterious, perhaps even awe inspiring phenomenon that transforms objects originally imbued with symmetrical beauty into junk".
