Soft materials are inherently flexible and make suitable candidates for soft robots intended for specific tasks that would otherwise not be achievable (e.g., smart grips capable of picking up objects without prior knowledge of their stiffness). Moreo

Plane wave propagation in an elastic lattice material follows regular patterns as dictated by the nature of the lattice symmetry and the mechanical configuration of the unit cell. A unique feature pertains to the loss of elastodynamic isotropy at fre

Magnetically-controlled and elastically-coupled multistable pendula are shown to serve as versatile structural analogs of ferroelectric crystals, mimicking atomic-level phenomena of domain patterning, domain nucleation, and Allen–Cahn-type domain w

Reconfigurable structures have gained importance in soft robotics, for deployable and shape-morphing systems, as well as in programmable metamaterials with controllable static and dynamic properties. The fundamental building block of all such archite

We present a theory for the dispersion of generated harmonics in a traveling nonlinear wave. The harmonics dispersion relation—derived by the theory—provides direct and exact prediction of the collective harmonics spectrum in the frequency-wavenu

International audience; Transition fronts, moving through solids and fluids in the form of propagating domain or phase boundaries, have recently been mimicked at the structural level in bistable architectures. What has been limited to simple one-dime

We show that propagating transitions fronts observed recently in multistable structural networks are analogous to solid–solid phase transformations in crystals and can therefore be described quantitatively as propagating shock fronts. We demonstrat

The introduction of nonlinearity alters the dispersion of elastic waves in solid media. In this paper, we present an analytical formulation for the treatment of finite-strain Bloch waves in one-dimensional phononic crystals consisting of layers with
