Multi-element metamaterial's design through the relaxed micromorphic model
Leonardo A. Perez Ramirez, Gianluca Rizzi, Angela Madeo
Exploring the dynamical response of mechanical metamaterials has gathered increasing attention in the last decades, enabling the design of microstructures exotically interacting wi…
Cosserat micropolar elasticity: classical Eringen vs. dislocation form
Ionel-Dumitrel Ghiba, Gianluca Rizzi, Angela Madeo +1
In this paper we do a comparative presentation of the linear isotropic Cosserat elastic model from two perspectives: the classical Mindlin-Eringen-Nowacki description in terms of a…
Unfolding engineering metamaterials design: relaxed micromorphic modeling of large-scale acoustic meta-structures
F. Demore, G. Rizzi, M. Collet +2
In this paper, we present a unit cell showing a band-gap in the lower acoustic domain. The corresponding metamaterial is made up of a periodic arrangement of this unit cell. We rig…
Modeling a labyrinthine acoustic metamaterial through an inertia-augmented relaxed micromorphic approach
Jendrik Voss, Gianluca Rizzi, Patrizio Neff +1
We present an inertia-augmented relaxed micromorphic model that enriches the relaxed micromorphic model previously introduced by the authors via a term in the…
