The generalized Floquet-Bloch spectrum for periodic thermodiffusive layered materials
Francesca Fantoni, Lorenzo Morini, Andrea Bacigalupo +1
The dynamic behaviour of periodic thermodiffusive multi-layered media excited by harmonic oscillations is studied. In the framework of linear thermodiffusive elasticity, periodic l…
On principal component analysis of the convex combination of two data matrices and its application to acoustic metamaterial filters
Giorgio Gnecco, Andrea Bacigalupo
In this short paper, a matrix perturbation bound on the eigenvalues found by principal component analysis is investigated, for the case in which the data matrix on which principal…
Variational-asymptotic homogenization of thermoelastic periodic materials with thermal relaxation
Deison Préve, Andrea Bacigalupo, Marco Paggi
A multiscale asymptotic homogenization method for periodic microstructured materials in presence of thermoelasticity with periodic spatially dependent one relaxation time is introd…
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…
Principal Component Analysis Applied to Gradient Fields in Band Gap Optimization Problems for Metamaterials
Giorgio Gnecco, Andrea Bacigalupo, Francesca Fantoni +1
A promising technique for the spectral design of acoustic metamaterials is based on the formulation of suitable constrained nonlinear optimization problems. Unfortunately, the stra…
