This work focuses on the enriched continuum modeling of finite-sized mechanical band-gap metamaterials, using the reduced relaxed micromorphic model (RRMM).
For finite-sized metamaterials, each constructed from a different unit cell ``cut", the choice of unit cell cut dictates the boundary effects that arise.
Coupling the RRMM with the method of interface forces, we are able to include the boundary effects in the reduced relaxed micromorphic framework.
Results are shown for the cases of modeling finite-size metamaterials constructed from different cuts, using the RRMM coupled with interface forces.
