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.…
