Effective description of anisotropic wave dispersion in mechanical band-gap metamaterials via the relaxed micromorphic model
Marco Valerio d'Agostino, Gabriele Barbagallo, Ionel-Dumitrel Ghiba +3
In this paper the relaxed micromorphic material model for anisotropic elasticity is used to describe the dynamical behavior of a band-gap metamaterial with tetragonal symmetry. Unl…

Relaxed micromorphic modeling of the interface between a homogeneous solid and a band-gap metamaterial: new perspectives towards meta-structural design
Angela Madeo, Gabriele Barbagallo, Manuel Collet +3
In the present paper, the material parameters of the isotropic relaxed micromorphic model derived for a specific metamaterial in a previous contribution are used to model its trans…
