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…
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…
A novel hydraulic fractures growth formulation
Francesca Fantoni, Alberto Salvadori
Propagation of a fluid-driven crack in an impermeable linear elastic medium under axis-symmetric conditions is investigated in the present work. The fluid exerting the pressure ins…
Wave propagation modeling in periodic elasto-thermo-diffusive materials via multifield asymptotic homogenization
Francesca Fantoni, Andrea Bacigalupo
A multifield asymptotic homogenization technique for periodic thermo-diffusive elastic materials is provided in the present study. Field equations for the first-order equivalent me…
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…
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…
