Time-modulated inerters as building blocks for nonreciprocal mechanical devices
Paolo Celli, Antonio Palermo
In this work, we discuss the realization of mechanical devices with non-reciprocal attributes enabled by inertia-amplifying, time-modulated mechanisms. Our fundamental building-blo…
A multiple scattering formulation for elastic wave propagation in space-time modulated metamaterials
Xingbo Pu, Alessandro Marzani, Antonio Palermo
Space-time modulation of material parameters offers new possibilities for manipulating elastic wave propagation by exploiting time-reversal symmetry breaking. Here we propose and v…
Topological edge states of quasiperiodic elastic metasurfaces
Xingbo Pu, Antonio Palermo, Alessandro Marzani
In this work, we investigate the dynamic behavior and the topological properties of quasiperiodic elastic metasurfaces, namely arrays of mechanical oscillators arranged over the fr…
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…
A multiple scattering formulation for finite-size flexural metasurfaces
Xingbo Pu, Antonio Palermo, Alessandro Marzani
We provide an analytical formulation to model the propagation of elastic waves in a homogeneous half-space supporting an array of thin plates. The technique provides the displaceme…
