Design Optimisation and Validation of Phononic Crystal Plates for Manipulation of Elastodynamic Guided Waves

This thesis proposes novel designs of phononic crystal plates (PhPs) allowing ultra-wide controllability frequency ranges of guided waves at low frequencies, with promising structural and tunability characteristics. It reports on topology optimization of bi-material-layered (1D) PhPs allowing maximi...
