Résumé au format pdf

Flexible mechanical metamaterials are compliant structures engineered to achieve unique properties via the large deformation of their components. While their static character has been studied extensively, the study of their dynamic properties is still at an early stage, especially in the nonlinear regime induced by their high deformability. Nevertheless, recent studies show that these systems provide new opportunities for the control of large amplitude elastic waves. I will highlight several of our recent results on the propagation of nonlinear waves in flexible elastic metamaterials and draw possible new research directions.
