The classification of materials into insulators and conductors has been shaken up by the discovery of topological insulators that conduct robustly at the edge but not in the bulk. In mechanics, designating a material as insulating or conducting amounts to asking if it is rigid or floppy. Although mechanical structures that display topological floppy modes have been proposed, they are all vulnerable to global collapse. Here, we design and build mechanical metamaterials that are stable and yet…

Controlling the deformation of metamaterials: Corner modes via topology
Topological metamaterials have invaded the mechanical world, demonstrating acoustic cloaking and waveguiding at finite frequencies and variable, tunable elastic response at zero frequency.
Localizing softness and stress along loops in 3D topological metamaterials
TLDR
The design of a 3D topological metamaterial without Weyl lines and with a uniform polarization that leads to an asymmetry between the number of soft modes on opposing surfaces is reported, suggesting a strategy for preprogramming failure and softness localized along lines in 3D, while avoiding extended soft Weyl modes.
Directional mechanical response in the bulk of topological metamaterials
Mechanical metamaterials are those structures designed to convey force and motion in novel and desirable ways. Recently, Kane and Lubensky showed that lattices at the point of marginal mechanical

TLDR
It is shown that the existence and form of a soft deformation directly determines floppy edge modes and phonon dispersion, and the soft strain is generalized to generate domain structures that allow further tuning of the material.

A recent connection between spring networks and quantum topological states is exploited to design origami with localized folding motions at boundaries and it is demonstrated how to generalize these topological design principles to two dimensions.
Topological mechanics of gyroscopic metamaterials

This work presents an experimental and theoretical study of an active metamaterial—composed of coupled gyroscopes on a lattice—that breaks time-reversal symmetry and presents a mathematical model that explains how the edge mode chirality can be switched via controlled distortions of the underlying lattice.
Observation of phononic helical edge states in a mechanical topological insulator
TLDR
The collective behavior of mechanical oscillators exhibiting the phenomenology of the quantum spin Hall effect is characterized, and the phononic edge modes are shown to be helical, and this may enable the design of topological acoustic metamaterials that can capitalize on the stability of the surface phonons as reliable wave guides.
