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…
Mitigation of Rayleigh-like waves in granular media via multi-layer resonant metabarriers
Rachele Zaccherini, Antonio Palermo, Alessandro Marzani +3
In this work, we experimentally and numerically investigate the propagation and attenuation of vertically polarized surface waves in an unconsolidated granular medium equipped with…
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…
Mitigation of seismic waves: metabarriers and metafoundations bench tested
Andrea Colombi, Rachele Zaccherini, Antonio Palermo
The article analyses two potential metamaterial designs, the metafoundation and the metabarrier, capable to attenuate seismic waves on buildings or structural components in a frequ…
