Breaking Scale Separation in Metamaterials' homogenization: Interface-Inertia-Enhanced Relaxed Micromorphic Model
Angela Madeo, Leonardo Perez, Mohammad Sarhil
The paper extends the relaxed micromorphic continuum model by adding a kinetic surface energy term to capture the inertial effects of macroscopic interfaces, allowing homogenized d…

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…
