This internship centers on investigating "membrane materials" for creating easily fabricated metamaterials with applications in acoustic and vibration damping, and potentially in mechanobiology. Metamaterials typically have unique properties but can be challenging to fabricate, so this project explores using simpler structures like foams as an alternative. The intern will study the dynamics of liquid and elastic membranes, which differ in behavior due to factors like surface tension and material elasticity. Through experiments and modeling, the goal is to create a unified framework for understanding these membranes and their interactions with fluids. This research is part of the ANR MEMBRANE project and aims to drive innovations in acoustics.
