Exploring metamaterials' structures through the relaxed micromorphic model: switching an acoustic screen into an acoustic absorber
Gianluca Rizzi, Manuel Collet, Félix Demore +3
While the design of always new metamaterials with exotic static and dynamic properties is attracting deep attention in the last decades, little effort is made to explore their inte…

Identification of second-gradient elastic materials from planar hexagonal lattices. Part I: Analytical derivation of equivalent constitutive tensors
G. Rizzi, F. Dal Corso, D. Veber +1
A second-gradient elastic (SGE) material is identified as the homogeneous solid equivalent to a periodic planar lattice characterized by a hexagonal unit cell, which is made up of…
