Breaking Scale Separation in Metamaterials' homogenization: Interface-Inertia-Enhanced Relaxed Micromorphic Model
Angela Madeo, Leonardo Perez, Mohammad Sarhil
Homogenized continuum models are widely used to describe wave propagation and band-gap behavior in mechanical metamaterials without explicitly resolving their microstructure. Their…
Unveiling the key role of Interfaces in the Design of finite-sized Metamaterial Structures
Svenja Hermann, Kévin Billon, Manuel Collet +1
This paper investigates the influence of interfaces on the performance of finite-sized mechanical metamaterial structures for vibration damping applications. The metamaterial struc…
Static size-effects meet the dynamic scattering properties of finite-sized mechanical metamaterials: a relaxed micromorphic study with parameter identification via two-stage static-dynamic optimization
Mohammad Sarhil, Leonardo Andres Perez Ramirez, Max Jendrik Voss +1
Mechanical metamaterials exhibit size-effects when a few unit-cells are subjected to static loading because no clear micro-macro scale separation holds and the characteristic lengt…
Time domain analysis of microstructured materials through the reduced relaxed micromorphic model
Gianluca Rizzi, Angela Madeo
Microstructured materials, such as architected metamaterials and phononic crystals, exhibit complex wave propagation phenomena due to their internal structure. While full-scale num…
Effective interface forces to model boundary effects in a finite-size metamaterial through the reduced relaxed micromorphic model
Plastiras Demetriou, Jendrik Voss, Angela Madeo
We use the reduced relaxed micromorphic model (RRMM) to capture the effective "bulk" dynamical response of finite size metamaterial specimens made out of a Labyrinthine unit cell.…
Design and experimental validation of a finite-size labyrinthine metamaterial for vibro-acoustics: enabling upscaling towards large-scale structures
Svenja Hermann, Kévin Billon, Alina-Michelle Parlak +3
In this paper, we present the design and experimental validation of a labyrinthine metamaterial for vibro-acoustic applications. Based on a 2D unit cell, different designs of finit…
