Origami provides both inspiration and potential solutions to the fabrication, assembly, and functionality of various structures and devices. Kinematic modeling of origamibased objects is essential to their analysis and design. Models for rigid origami, in which all planar faces of the sheet are rigid and folds are limited to straight creases having only zeroth-order geometric continuity, are available in the literature. Many of these models include constraints on the fold angles to ensure that any initially closed strip of faces is not torn during folding. However, these previous models are not intended for structures with non-negligible fold thickness or with maximum curvature at the folds restricted by material or structural limitations. Thus, for general structures, creased folds of merely zeroth-order geometric continuity are not appropriate idealizations of structural response, and a new approach is needed. In this work, a novel model analogous to those for rigid origami with creased folds is presented for sheets having realistic folds of nonzero surface area and exhibiting higher-order geometric continuity, here termed smooth folds. The geometry of smooth folds and constraints on their associated shape variables are presented. A numerical implementation of the model allowing for kinematic simulation of sheets having arbitrary fold patterns is also described. Simulation results are provided showing the capability of the model to capture realistic kinematic response of origami sheets with diverse fold patterns.

“…Ongoing research activities include investigating the implementation of structurally insulated panels (SIP) for military barracks [9][10]. The art of origami offers inspiration for a wide array of engineering applications [11], particularly for thermally insulated, deployable sheltering topologies as it offers a means for packaging rigid wall shelters in small volumes [12]. Quaglia et al [3,4] have proposed a viable solution for a deployable origami-inspired shelter with enhanced energy performance that has been experimentally tested [13][14].…”

“…Quaglia et al [3,4] have proposed a viable solution for a deployable origami-inspired shelter with enhanced energy performance that has been experimentally tested [13][14]. This solution is comprised of sandwich panels [fiber reinforced polymer (FRP) faces and a foam core] which offer a high strength-to-weight ratio and thermal insulation for energy efficiency in heating and cooling [4,12]. When using high cost material such as advanced composites, however, there is an advantage in minimizing wasted material in the manufacturing process.…”

Lightweight, thermally insulated, temporary shelters are essential for disaster relief and military operations. To minimize cost and increase sustainability, it is advantageous to reduce wasted material in manufacturing these shelters. This paper investigates quilt patterns-designs of interlocking geometric shapes-as inspiration for structural topologies that can be manufactured from flat sheets with minimal wasted material (shape interfaces serve as cut and fold lines). A series of quilt-inspired concepts based on established quilt patterns are developed into structural topologies using shape grammar rules. The detailed finite element analysis and design of three concepts is presented. To achieve a lightweight, thermally insulated design, the structures are comprised of sandwich panels (fiber-reinforced polymer faces and a foam core). The performance of each design is compared to an existing rigid wall shelter, demonstrating the efficacy of quilt-inspired forms. This paper is the first investigation of quilting as inspiration for structural systems.

Origami has enabled new approaches to the fabrication and functionality of multiple structures. Current methods for origami design are restricted to the idealization of folds as creases of zerothorder geometric continuity. Such an idealization is not proper for origami structures of non-negligible fold thickness or maximum curvature at the folds restricted by material limitations. For such structures, folds are not properly represented as creases but rather as bent regions of higher-order geometric continuity. Such fold regions of arbitrary order of continuity are termed as smooth folds. This paper presents a method for solving the following origami design problem: given a goal shape represented as a polygonal mesh (termed as the goal mesh), find the geometry of a single planar sheet, its pattern of smooth folds, and the history of folding motion allowing the sheet to approximate the goal mesh. The parametrization of the planar sheet and the constraints that allow for a valid pattern of smooth folds are presented. The method is tested against various goal meshes having diverse geometries. The results show that every determined sheet approximates its corresponding goal mesh in a known folded configuration having fold angles obtained from the geometry of the goal mesh.
