Abstract
Arisen from the geometric arrangements of panels and creases, unique mechanical properties such as foldability endow origami with promise for developing novel tunable and functional structural systems. To promote engineering applications of origami, a simplified but effective approach for investigation of the nonlinear mechanical behavior of non-rigid origami structures is essential. We propose a fully nonlinear, displacement-based formulation, for constructing quasi-static finite element analyses of origami structures based on a previously established bar-and-hinge simplification. The formulation leads to an efficient and robust numerical approach for predicting large displacements and large local deformations of origami structures. Comparison between actual paper-made models and numerical simulations hints the ability of the proposed approach in capturing key features of origami deformation. Thus the current work builds up a connection between theory and practice of origami structures, which has the potential to impact design, education, and applications of origami.
