Simulation of paper-based curved crease origami structures

Abstract

Origami structure numerical simulations are important in analyzing deployable structures used in aerospace. The analytical equations for the edge curved motion are first considered and then a numerical modeling method is proposed. The numerical modeling and the experimental study are focused on the behavior of an 80gsm copier paper Miura Ori curved crease model with a perforated crease. The crease stiffness for the numerical modeling for a perforated 80gsm copier paper is assumed from the straight crease folding stiffness value found in the experimental setup. The numerical model is validated by reconstructing the experimental specimen surface mesh using a LiDAR scan. The result of the paper shows the numerical model for the curved crease folding shows a good resemblance compared with the experimental model setup.
