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…
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…
Textile hinges enable extreme properties of mechanical metamaterials
A. S. Meeussen, G. Bordiga, A. X. Chang +4
Mechanical metamaterials -- structures with unusual properties that emerge from their internal architecture -- that are designed to undergo large deformations typically exploit lar…
Automated discovery of reprogrammable nonlinear dynamic metamaterials
Giovanni Bordiga, Eder Medina, Sina Jafarzadeh +4
Harnessing the rich nonlinear dynamics of highly-deformable materials has the potential to unlock the next generation of functional smart materials and devices. However, unlocking…
Tensile material instabilities in elastic beam lattices lead to a bounded stability domain
G. Bordiga, D. Bigoni, A. Piccolroaz
Homogenization of the incremental response of grids made up of preloaded elastic rods leads to homogeneous effective continua which may suffer macroscopic instability, occurring at…
A way to hypo-elastic artificial materials without a strain potential and displaying flutter instability
G. Bordiga, A. Piccolroaz, D. Bigoni
Cauchy-elastic solids include hyper-elasticity and a subset of elastic materials for which the stress does not follow from a scalar strain potential. More in general, hypo-elastic…
