Acoustic waveguide filters made up of rigid stacked materials with elastic joints
Andrea Bacigalupo, Luigi Gambarotta, Marco Lepidi +1
The acoustic dispersion properties of monodimensional waveguide filters can be assessed by means of the simple prototypical mechanical system made of an infinite stack of periodic…
Complex frequency band structure of periodic thermo-diffusive materials by Floquet-Bloch theory
Andrea Bacigalupo, Maria Laura De Bellis, Giorgio Gnecco
This work deals with the micromechanical study of periodic thermo-diffusive elastic multi-layered materials, which are of interest for the fabrication of solid oxide fuel cells (SO…
Dynamic asymptotic homogenization for periodic viscoelastic materials
Rosaria Del Toro, Andrea Bacigalupo, Marco Paggi
A non-local dynamic homogenization technique for the analysis of a viscoelastic heterogeneous material which displays a periodic microstructure is herein proposed. The asymptotic e…
Generalized micropolar continualization of 1D beam lattices
Andrea Bacigalupo, Luigi Gambarotta
The enhanced continualization approach proposed in this paper is aimed to overcome some drawbacks observed in the homogenization of beam lattices. To this end an enhanced homogeniz…
Identification of higher-order continua equivalent to a Cauchy elastic composite
A. Bacigalupo, M. Paggi, F. Dal Corso +1
A heterogeneous Cauchy elastic material may display micromechanical effects that can be modeled in a homogeneous equivalent material through the introduction of higher-order elasti…
Design of thermo-piezoelectric microstructured bending actuators via multi-field asymptotic homogenization
Francesca Fantoni, Andrea Bacigalupo, Marco Paggi
The use of integrated MicroElectroMechanical systems (MEMS) is recently spread thanks to their improved sensitivity, accuracy and reliability. Accurate preliminary computations bor…
Bloch wave filtering in tetrachiral materials via mechanical tuning
Francesca Vadalà, Andrea Bacigalupo, Marco Lepidi +1
The periodic cellular topology characterizing the microscale structure of a heterogeneous material may allow the finest functional customization of its acoustic dispersion properti…
Acoustic wave polarization and energy flow in periodic beam lattice materials
Andrea Bacigalupoa, Marco Lepidi
The free propagation of acoustic plane waves through cellular periodic materials is generally accompanied by a flow of mechanical energy across the adjacent cells. The paper focuse…
