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 device 606 $aSmart structures$vCongresses 606 $aSmart materials$vCongresses 606 $aStructural control (Engineering)$vCongresses 606 $aAerospace engineering$vCongresses 615 0$aSmart structures 615 0$aSmart materials 615 0$aStructural control (Engineering) 615 0$aAerospace engineering 676 $a624.1 701 $aWagg$b David$0521396 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910877144003321 996 $aAdaptive structures$94186290 997 $aUNINA
