Enhanced dynamic homogenization of hexagonally packed granular materials with elastic interfaces
Andrea Bacigalupo, Luigi Gambarotta
It is well known that the classical energetically consistent micropolar model has limits in simulating the frequency band structure of packed granular materials (see Merkel et al.,…
A dynamic high-frequency consistent continualization of beam-lattice materials
Andrea Bacigalupo, Luigi Gambarotta
The main purpose of the present paper is to solve the thermodynamic inconsistencies that result when deriving equivalent micropolar models of periodic beam-lattice materials throug…
Chiral two-dimensional periodic blocky materials with elastic interfaces: auxetic and acoustic properties
Andrea Bacigalupo, Luigi Gambarotta
Two novel chiral block lattice topologies are here conceived having interesting auxetic and acoustic behavior. The architectured chiral material is made up of a periodic repetition…
Identification of non-local continua for lattice-like materials
Andrea Bacigalupo, Luigi Gambarotta
The paper is focused on the dynamic homogenization of lattice-like materials with lumped mass at the nodes to obtain energetically consistent models providing accurate descriptions…
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…
