Transmissibility, boundary-guided waves, and representative unit cell choice in finite-sized metamaterials
Plastiras Demetriou, Gianluca Rizzi
The implications of selecting different unit cells are often overlooked in both direct studies of microstructured materials and their homogenized equivalents. Investigating the eff…
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 surface forces and non-coherent interfaces within the reduced relaxed micromorphic modeling of finite-size mechanical metamaterials
L. A. Perez Ramirez, F. Erel-Demore, G. Rizzi +2
This paper introduces for the first time the concepts of non-coherent interfaces and microstructure-driven interface forces in the framework of micromorphic elasticity. It is shown…
Green's functions for the isotropic planar relaxed micromorphic model -- concentrated force and concentrated couple
Panos Gourgiotis, Gianluca Rizzi, Peter Lewintan +4
We derive the Green's functions (concentrated force and couple in an infinite space) for the isotropic planar relaxed micromorphic model. Since the relaxed micromorphic model parti…
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…
Reduced relaxed micromorphic modeling of harmonically loaded metamaterial plates: investigating boundary effects in finite-size structures
Plastiras Demetriou, Gianluca Rizzi, Angela Madeo
In this paper, we propose an approach for describing wave propagation in finite-size microstructured metamaterials using a reduced relaxed micromorphic model. This method introduce…
