We create mechanical metamaterials whose response to uniaxial compression can be programmed by lateral confinement, allowing monotonic, nonmonotonic, and hysteretic behavior. These functionalities arise from a broken rotational symmetry which causes highly nonlinear coupling of deformations along the two primary axes of these metamaterials. We introduce a soft mechanism model which captures the programmable mechanics, and outline a general design strategy for confined mechanical metamaterials…

Transformable topological mechanical metamaterials

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.

The extreme mechanics of viscoelastic metamaterials

Mechanical metamaterials made of flexible building blocks can exhibit a plethora of extreme mechanical responses, such as negative elastic constants, shape-changes, programmability, and memory. To

Three-Dimensionally Printed Mechanical Metamaterials With Thermally Tunable Auxetic Behavior

Mechanical metamaterials exhibiting negative Poisson's ratio (expanding, rather than contracting, in the direction perpendicular to an applied force) typically do not retain the ability to behave as

Vibrant times for mechanical metamaterials

Metamaterials are man-made designer matter that obtains its unusual effective properties by structure rather than chemistry. Building upon the success of electromagnetic and acoustic metamaterials,

Snapping Mechanical Metamaterials under Tension

A snapping mechanical metamaterial is designed, which exhibits a sequential snap-through behavior under tension, and can be altered by tuning the architecture of the snapping segments to achieve a range of nonlinear mechanical responses, including monotonic, S-shaped, plateau, and non-monotonic snap-Through behavior.

Tensional acoustomechanical soft metamaterials

A theoretical acoustomechanical model is established to describe the programmable mechanics of such soft metamaterial, and the first- and second-order tangential stiffness of its force versus stretch curve to boundary different behaviors that appear during deformation are introduced.

Programmable mechanical metamaterials: the role of geometry.

This study provides precise guidelines for the rational design of programmable biholar metamaterials, tailored to specific applications, and indicates that the widest range of programmability arises for moderate values of both t and χ.

Topological defects steer stresses in two- and three-dimensional combinatorial mechanical metamaterials.

Mechanical metamaterials present a promising platform for seemingly impossible mechanics. They often require frustration of their elementary building blocks, yet a comprehensive understanding of its



International Journal of Solids and Structures

The manufacturing of multistable shells has been dominated by the use of pre-stressed and composite materials. Here we advocate the use of common materials through a simple design that requires no
