We develop a geometric approach to understand the mechanics of perforated thin elastic sheets, using the method of strain-dependent image elastic charges. This technique recognizes the buckling response of a hole under an external load as a geometrically tuned mechanism of stress relief. We use a diagonally pulled square paper frame as a model system to quantitatively test and validate our approach. Specifically, we compare nonlinear force-extension curves and global displacement fields in… 
Nonlinear mechanics of thin frames.
TLDR
The technique of elastic charges is developed to address a variety of elastic problems involving thin sheets with perforations, focusing on frames with sharp corners, and finds that holes generate elastic defects (partial disclinations), which act as sources of geometric incompatibility.
On local kirigami mechanics II: Stretchable creased solutions
Following on Part I of this work series on local kirigami mechanics, we present a study of a discretely creased mechanism as a model to investigate the mechanics of the basic geometric building block
Geometric charges and nonlinear elasticity of two-dimensional elastic metamaterials
TLDR
An intuitive and quantitatively accurate conceptual formalism is developed that maps the two-dimensional elastic problem into that of nonlinear interaction of elastic charges, which offers an intuitive conceptual framework, qualitatively explaining the linear response, the onset of mechanical instability, and aspects of the postinstability state.
Geometric charges and nonlinear elasticity of soft metamaterials.
Problems of flexible mechanical metamaterials, and highly deformable porous solids in general, are rich and complex due to nonlinear mechanics and nontrivial geometrical effects. While numeric
Design of Rigidity and Breaking Strain for a Kirigami Structure with Non-Uniform Deformed Regions
TLDR
The results show that it is possible to theoretically design the mechanical characteristics of a kirigami structure, and that such a design can well predict the influence of cuts, which induce non-uniform deformation at both ends.
On local kirigami mechanics I: Isometric conical solutions
Abstract Over the past decade, kirigami—the Japanese art of paper cutting—has been playing an increasing role in the emerging field of mechanical metamatertials and a myriad of other mechanical
Cutting holes in bistable folds
A folded disk is bistable, as it can be popped through to an inverted state with elastic energy localized in a small, highly-deformed region on the fold. Cutting out this singularity relaxes the
Critical transitions in the shape morphing of kirigami metallic glass
Abstract Kirigami, the ancient Japanese paper cutting technique, has been applied to achieve high stretchability and low energy loss of designed metallic glass. Despite the exploration of the

Elastic multipole method for describing deformation of infinite two-dimensional solids with circular inclusions.
TLDR
A method is presented that expands the induced polarization in a series of elastic multipoles, which systematically takes into account the interactions of inclusions and holes with the external stress field and also between them, and shows good agreement with both linear finite element simulations and experiments.

Buckling-Induced Kirigami.
TLDR
The proposed buckling-induced pop-up strategy points to a simple route for manufacturing complex morphable structures out of flat perforated sheets, including kirigami sheets comprising periodic distribution of cuts and permanent folds.
Kirigami actuators.
TLDR
This work shows how the interactions between non-propagating cracks can enable either lift or rotation, and uses a combination of experiments, theory, continuum computational analysis, and molecular dynamics simulations to provide mechanistic insights into the geometric and topological design of kirigami actuators.
Initial rigid response and softening transition of highly stretchable kirigami sheet materials
TLDR
The physical origins of the transition and mechanical regimes, which are revealed to be governed by simple scaling laws, could be useful for controlling and designing the mechanical response of sheet materials including cell sheets for medical regeneration and relevant to the development of materials with tunable stiffness and mechanical force sensors.
Elastic interactions between two-dimensional geometric defects.
TLDR
This paper applies a methodology applicable to a wide range of localized two-dimensional sources of stress to two physical systems: shear-induced failure of amorphous materials and the mechanical interaction between contracting cells.

TLDR
By taking inspiration from kirigami, it is shown that a network of notches made in rigid nanocomposite and other composite sheets by top-down patterning techniques prevents unpredictable local failure and increases the ultimate strain of the sheets from 4 to 370%.
