Mechanical metamaterials exhibit exotic properties that emerge from the interactions of many nearly rigid building blocks. Determining these properties theoretically has remained an open challenge outside a few select examples. Here, for a large class of periodic and planar kirigami, we provide a coarse-graining rule linking the design of the panels and slits to the kirigami's macroscale deformations. The procedure gives a system of nonlinear partial differential equations expressing geometric…

Conformal elasticity of mechanism-based metamaterials

The authors present an analytical framework for a canonical mechanism that can not only predict, but also precisely control deformation in flexible metamaterials, and demonstrates a general principle in which mechanisms can generate special classes of soft deformations.

Modeling planar kirigami metamaterials as generalized elastic continua

Planar kirigami metamaterials dramatically change their shape through a coordinated motion of nearly rigid panels and flexible slits. Here, we study a model system for mechanism-based planar kirigami

Some results on the Guest-Hutchinson modes and periodic mechanisms of the Kagome lattice metamaterial

Lattice materials are interesting mechanical metamaterials, and their mechanical properties are often related to the presence of mechanisms. The existence of periodic mechanisms can be indicated by

We present an additive approach for the inverse design of kirigami-based mechanical metamaterials by focusing on the design of the negative spaces instead of the kirigami tiles. By considering each

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.

Until now, no third gradient theory has been proposed to describe the homogenized energy associated with a microscopic structure. In this paper, we prove that this is possible using pantographic-type
