It reports on topology optimization of bi-material-layered (1D) PhPs allowing maximized relative bandgap width (RBW) at target filling fractions and demonstrates multiscale functionality of gradient PhPs. It also introduces a multi-objective topology optimization method for 2D porous PhPs allowing both maximized RBW and in-plane stiffness and addresses the critical role of considering stiffness in designing porous PhPs. The multi-objective topology optimization method is then expanded for designing 2D porous PhPs with deformation induced tunability. A variety of innovative designs are introduced which their maximized broadband RBW is enhanced by, is degraded by or is insensitive to external finite deformation. Not only does this book address the challenges of new topology optimization methods for computational design of phononic crystals; yet, it demonstrated the suitability and applicability of the topological designs by experimental validation. Furthermore, it offers a comprehensive review of the existing optimization-based approaches for the design of finite non-periodic acoustic metamaterial structures, acoustic metamaterial lattice structures and acoustic metamaterials under perfect periodicity.  . 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aVibration 606 $aDynamics 606 $aDynamics 606 $aMaterials science 606 $aEngineering design 606 $aVibration, Dynamical Systems, Control$3https://scigraph.springernature.com/ontologies/product-market-codes/T15036 606 $aCharacterization and Evaluation of Materials$3https://scigraph.springernature.com/ontologies/product-market-codes/Z17000 606 $aEngineering Design$3https://scigraph.springernature.com/ontologies/product-market-codes/T17020 615 0$aVibration. 615 0$aDynamics. 615 0$aDynamics. 615 0$aMaterials science. 615 0$aEngineering design. 615 14$aVibration, Dynamical Systems, Control. 615 24$aCharacterization and Evaluation of Materials. 615 24$aEngineering Design. 676 $a620.11 700 $aHedayatrasa$4aut$4http://id.loc.gov/vocabulary/relators/aut$02016148 701 $a Saeid.$02011593 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910299580503321 996 $aDesign Optimisation and Validation of Phononic Crystal Plates for Manipulation of Elastodynamic Guided Waves$94807154 997 $aUNINA
