A Nonlinear Damped Metamaterial: Wideband Attenuation with Nonlinear Bandgap and Modal Dissipation
Bao Zhao, Henrik R. Thomsen, Xingbo Pu +6
In this paper, we incorporate the effect of nonlinear damping with the concept of locally resonant metamaterials to enable vibration attenuation beyond the conventional bandgap ran…
Time-sharing Orbit Jump and Energy Harvesting in Nonlinear Piezoelectric Energy Harvesters Using a Synchronous Switch Circuit
Bao Zhao, Jiahua Wang, Guobiao Hu +3
Nonlinearity has enabled energy harvesting to advance towards higher power output and broader bandwidth in monostable, bistable, and multistable systems. However, challenges in ope…
Boundless metamaterial experimentation: physical realization of a virtual periodic boundary condition
Henrik R. Thomsen, Bao Zhao, Andrea Colombi
We experimentally implement a virtual geometric periodicity in an elastic metamaterial. First, unwanted boundary reflections at the domain ends are cancelled through the iterative…
A Graded Metamaterial for Broadband and High-capability Piezoelectric Energy Harvesting
Bao Zhao, Henrik R. Thomsen, Jacopo M. De Ponti +5
This work studies a broadband graded metamaterial, which integrates the piezoelectric energy harvesting function targeting low-frequency structural vibrations, lying below 100 Hz.…
Stress-optimized inertial amplified metastructure with opposite chirality for vibration attenuation
Rachele Zaccherini, Andrea Colombi, Antonio Palermo +2
In this work, we investigate the dynamics and attenuation properties of a one-dimensional inertial amplified lattice with opposite chirality. The unit cell of the structure consist…
Attenuation of surface modes in granular media
R. Zaccherini, A. Palermo, A. Marzani +3
In this work, an unconsolidated granular medium, made of silica microbeads, is experimentally tested in a laboratory setting. The objective is to investigate the attenuation mechan…
