Abstract
The goal of this dissertation is to integrate multiphysics matter with mechanics-driven design to create a class of structurally integrated inclusions and resonators for vibration suppression and wave control. The formulation of this new class of structurally integrated inclusions and resonators results from assessment of host structure constraints, vibration suppression mechanisms, and the capability to couple with elastic wave propagation. Classical concepts for vibration and wave attenuation, including tuned mass damper (TMD), constrained layered damping (CLD), and bandgap, are able to be manifest in these new material platforms by incorporation of the appropriate relations among dimensions, boundaries, and degrees-of-freedom. Rather than rely on the conventional needs for large mass ratios, large coverage areas, or limited operating frequency ranges to leverage these vibration and wave attenuation mechanisms, this research harnesses the structural integration of inclusions and resonators for lightweight, small-scale solutions for elastic vibrational energy control. The dissertation investigates the foundations and mechanisms of structurally integrated resonators and inclusions for controlling vibration and elastic wave in structural systems. The structural systems include elastomeric cylindrical inclusions embedded within tubes, lightweight resonators attached to panels, moment-coupled resonators in plates, and spatio-temporally modulated beams. For the elastomeric cylindrical inclusions, the strategically combined concepts of TMD and CLD are investigated and identified multiple pathways for tube vibration suppression to increase the versatility of inclusions. The unique interactions between host structures and applied resonators are deciphered, which reveals how to transfer vibration energy to dissipative resonators when exploiting sparsely distributed resonators on host structures. Regarding the modulated beams, the spatial and temporal exchange of energy among patches and host structures is explored, which examines the non-reciprocal wave propagation property and further enhances the flexibility of controlling wave propagation. The dynamic characteristics in the inclusions, resonators, and spatio-temporally modulated structures are uncovered to govern the mechanisms of vibration attenuation and wave control. The relations between applied resonator parameters and system characteristics, connections of physical concepts in various fields, and physical mechanisms discovered in this dissertation will open new avenues for vibration attenuation and wave propagation control.
