Harnessing extreme wave events in non-linear flexible elastic metamaterials – ExFLEM

Submission summary

This project aims at studying, observing and harnessing extreme wave events using continuous wave excitations in non-linear flexible elastic metamaterials. While the propagation of soliton-type impulses has been successfully studied in recent years within the so-called rotating square architectures, the response of such flexible metamaterials to periodic or continuous wave excitations remains virtually unexplored. This regime presents a strong connection with applications such as high amplitude vibrations and noise control, energy harvesting, or with challenges such as the actuation, locomotion or structural reconfiguration. Without loss of generality, flexible metamaterials here constitute an ideal generic exploratory platform. In particular, we propose to study and use extreme events (e.g. rogue waves), as new strategies for actuating and reconfiguring bistable metamaterials, among others.
