Bar and hinge models, which approximate the structural characteristics of origami, have been used as early as 2011, but in this paper, Professor Filipov and others improve the model even further by introducing new combinations of bars and hinges, culminating in the N5B8 model. The paper focuses on the following key aspects:
- The N5B8 model simulates three distinct behaviors: stretching and shearing of thin sheet panels; bending of the initially flat panels; and bending along prescribed fold lines.
- The N5B8 model is simple and efficient, yet it can provide realistic representation of stiffness characteristics and deformed shapes of origami structures.
