Metastructures for vibration suppression (INVITED)

Abstract eng:
Traditional damping methods such as viscoelastic treatments as well as the more recent metamaterial inspired approaches are not scalable, fail at low frequency, are temperature sensitive and are relatively narrowband. This talk examines the expansion of the metamaterial concept of repeated cells to address the aforementioned issues. This talk examines a metamaterial inspired approach to creating new structural systems with superior vibration damping properties by embedding inserts into a structure to create a system with low frequency, broadband-damping and vibration suppression properties across multiple scales. In addition to optimizing chiral based meta material configurations, two novel insert configurations combined with a magnetic field to produce nonlinear inserts that greatly improve the design space of metamaterial inspired structures are illustrated. These new configurations are scalable from micrometers to meters. Simple analytical models are presented, 3-D printed examples are manufactured and the models validated against experiments.
