Abstract:
The realization of weight reduction with novel lightweight materials and structures is a key issue facing the development of modern ecological society as well as a challenge facing scientists and engineers worldwide. From largescale structures such as oil platforms, high speed trains, aircraft fuselages, satellites and supersonic space vehicles to small scale electronic devices, optimization towards compactness and lightweight has become an integral part of their development. Further, the reduction of weight is often accompanied by mulitfunctional requirements such as high strength/stiffness, efficient heat dissipation, noise/vibration/damping control and actuation/sensing, demanding cross disciplinary research efforts across materials science, solid/fluid mechanics, physics, heat transfer, acoustics and applied mathematics.
