The analysis and design of adaptive structures requires a highly multi-disciplinary approach which includes elements of structures, materials, dynamics, control, design and inspiration taken from biological systems. Development of adaptive structures has been taking place in a wide range of industrial applications, but is particularly advanced in the aerospace and space technology sector with morphing wings, deployable space structures; piezoelectric deviceSmart structuresCongressesSmart materialsCongressesStructural control (Engineering)CongressesAerospace engineeringCongressesSmart structuresSmart materialsStructural control (Engineering)Aerospace engineering624.1Wagg David521396MiAaPQMiAaPQMiAaPQBOOK9910877144003321Adaptive structures4186290UNINA
