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…
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…
Binary classification of spoken words with passive phononic metamaterials
Tena Dubček, Daniel Moreno-Garcia, Thomas Haag +11
Mitigating the energy requirements of artificial intelligence requires novel physical substrates for computation. Phononic metamaterials have a vanishingly low power dissipation an…
Locally resonant metasurfaces for shear waves in granular media
Rachele Zaccherini, Andrea Colombi, Antonio Palermo +5
In this article the physics of horizontally polarized shear waves travelling across a locally resonant metasurface in an unconsolidated granular medium is experimentally and numeri…
