From frequency-dependent models to frequency-independent enriched continua for mechanical metamaterials
Gianluca Rizzi, Marco Valerio d'Agostino, Jendrik Voss +3
Mechanical metamaterials have recently gathered increasing attention for their uncommon mechanical responses enabling unprecedented applications for elastic wave control. To model…
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…
Boundary and interface conditions in the relaxed micromorphic model: exploring finite-size metastructures for elastic wave control
Gianluca Rizzi, Marco Valerio d'Agostino, Patrizio Neff +1
In this paper, we establish well-posed boundary and interface conditions for the relaxed micromorphic model that are able to unveil the scattering response of fully finite-size met…
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 scale-independent material parameters in the relaxed micromorphic model through model-adapted first order homogenization
Patrizio Neff, Bernhard Eidel, Marco Valerio d'Agostino +1
We rigorously determine the scale-independent short range elastic parameters in the relaxed micromorphic generalized continuum model for a given periodic microstructure. This is do…
