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…
Phonon controlled mechanical memory via pinning and depinning of transition waves
Samuele Ferracin, Dengge Jin, Vincent Tournat +1
Multistable mechanical metamaterials enable programmable transitions between discrete stable states through propagating kink transition waves (TWs). Yet controlling these kinks typ…
Effect of discreteness on domain wall stability in a plate coupled to a foundation of bistable elements
Dengge Jin, Samuele Ferracin, Vincent Tournat +1
Surfaces and structures capable of multiple stable configurations have attracted growing interest for on-demand shape morphing. In this work, we consider an elastic compliant plate…
Vibrational Transportation of Deformable Axisymmetric Particles
Marina E. Terzi, Vladislav V. Aleshin, Jules Ghesqui`ere +1
A particle on a substrate supporting a surface acoustic wave can experience horizontal drift excited by the dry friction force. The effect is referred to as vibrational transportat…
Experimental study of the acoustic frequency-up conversion effect by nonlinear thin plates
Alexis Mousseau, Soizic Terrien, Vincent Tournat
Classical methods of sound absorption present fundamental limits that can be overcome by using nonlinear effects. Thin clamped plates have been identified as strongly nonlinear ele…
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…
A theoretical framework for physically-realizable kagome metamaterials and its implications on dualities and topological edge modes
Weijian Jiao, Hang Shu, Vincent Tournat
Since the discovery of topological modes in idealized ball-and-spring kagome lattices, significant efforts have been devoted to realizing mechanical analogues of these ideal lattic…
