Design of tunable acoustic metamaterials with periodic piezoelectric microstructure
Andrea Bacigalupo, Maria Laura De Bellis, Diego Misseroni
An innovative special class of tunable periodic metamaterials is designed, suitable for realising high-performance acoustic filters. The metamaterial is made up of a phononic cryst…
Free and forced wave propagation in beam lattice metamaterials with viscoelastic resonators
F Vadalà, A Bacigalupo, M Lepidi +1
Beam lattice materials are characterized by a periodic microstructure realizing a geometrically regular pattern of elementary cells. In these microstructured materials, the dispers…
Machine-learning techniques for the optimal design of acoustic metamaterials
Andrea Bacigalupo, Giorgio Gnecco, Marco Lepidi +1
Recently, an increasing research effort has been dedicated to analyse the transmission and dispersion properties of periodic acoustic metamaterials, characterized by the presence o…
A phase field approach for damage propagation in periodic microstructured materials
Francesca Fantoni, Andrea Bacigalupo, Marco Paggi +1
In the present work, the evolution of damage in periodic composite materials is investigated through a novel finite element-based multiscale computational approach. The methodology…
A novel layered topology of auxetic materials based on the tetrachiral honeycomb microstructure
Ferdinando Auricchio, Andrea Bacigalupo, Luigi Gambarotta +3
Microstructured honeycomb materials may exhibit exotic, extreme and tailorable mechanical properties, suited for innovative technological applications in a variety of modern engine…
Characterization of hybrid piezoelectric nanogenerators through dynamic asymptotic homogenization
Maria Laura De Bellis, Andrea Bacigalupo, Giorgio Zavarise
In the framework of energy scavenging for applications in flexible/strechable electronics, hybrid piezoelectric nanogenerators, made up with Zinc oxyde nanorods, embedded in a poly…
