Wave-based reading of mechanical memory in multistable mass-in-mass metamaterials
Audrey Watkins, Giovanni Bordiga, Vincent Tournat +1
Mechanical metamaterials with integrated bistable elements have emerged as promising platforms for mechanical information storage, where transitions between stable states encode in…
Conformal Elastodynamics in 2D Dilational Metamaterials
Neel Singh, Audrey A. Watkins, Giovanni Bordiga +3
Flexible mechanical structures can undergo large deformations under small loads, enabling large, complex, and nonlinear wave responses under finite-frequency driving. Here, we stud…
Transition Waves in Mechanical Metamaterials with Neighbor-Programmable Energy Landscapes
Eleonore Duval, Giada Risso, Alex Zhang +2
Transition waves in mechanical metamaterials manifest themselves as propagating interfaces between different stable states in lattices composed of arrays of coupled, intrinsically…
Nonlinear mechanical metamaterial cloaks
Giovanni Bordiga, Jean-Gabriel Argaud, Audrey A. Watkins +2
The concept of cloaking -- hiding objects from external detection -- has seen wide success in linear systems. Yet, translating these advancements to nonlinear mechanical systems re…
Arbitrary mechanical memory encoding via nonlinear waves in bistable metamaterials
Audrey A. Watkins, Giovanni Bordiga, Mingxing Mu +2
Mechanical metamaterials composed of bistable elements have recently emerged as promising platforms for mechanical memory. Traditional approaches to writing information in these sy…
