Origami structures are mechanical metamaterials with properties that arise almost exclusively from the geometry of the constituent folds and the constraint of piecewise isometric deformations. Here we characterize the geometry and planar and nonplanar effective elastic response of a simple periodically folded Miura-ori structure, which is composed of identical unit cells of mountain and valley folds with four-coordinated ridges, defined completely by two angles and two lengths. We show that the…

Foldable cones as a framework for nonrigid origami.
This work studies the elastic behavior of isometric f-cones for any deflection and crease mechanics, which introduce nonlinear corrections to a linear model studied previously, and tests the inextensibility hypothesis by means of a continuous numerical model that includes both the extended nature of the creases, stretching and bending deformations of the panels.
Origami based Mechanical
We describe mechanical metamaterials created by folding flat sheets in the tradition of origami, the art of paper folding, and study them in terms of their basic geometric and stiffness properties,

Folding to Curved Surfaces: A Generalized Design Method and Mechanics of Origami-based Cylindrical Structures
An in-plane design method is proposed to approximate curved surfaces of interest with generalized Miura-ori units and generates multiple types of cylindrical structures, extending the design space of mechanical metamaterials and providing a basis for their practical applications in science and engineering.
Topological transitions in the configuration space of non-Euclidean origami.
It is shown that the configuration space of nonintersecting, oriented vertices with positive Gaussian curvature decomposes into disconnected subspaces; there is no pathway between them without tearing the origami, providing a new, and only partially explored, mechanism by which the mechanics and folding of an origami structure could be controlled.
Hidden symmetries generate rigid folding mechanisms in periodic origami
This work considers origami sheets with periodic but otherwise generic, asymmetric triangular faces and shows they exhibit nonlinear folding motions which transform sheets through two-dimensional families of cylindrical configurations, with the addition of quadrilateral faces restricting sheets to one-dimensional subsets of configurations.

The framework developed in this paper is suitable for determination of other properties of ridges such as their interaction or behavior under various types of loading and is expected to have broad importance in describing forced crumpling of thin sheets.

Simulation of clothing with folds and wrinkles
Novel contributions include a mixed explicit/implicit time integration scheme, a physically correct bending model with (potentially) nonzero rest angles for pre-shaping wrinkles, an interface forecasting technique that promotes the development of detail in contact regions, a post-processing method for treating cloth-character collisions that preserves folds and wrinkles, and a dynamic constraint mechanism that helps to control large scale folding.
