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…
