Fig. 4: Deployment mechanics of a reconfigurable bellows origami EM waveguide.
a Unit bellows model with one-eighth highlighted portion under study. b Plots of non-dimensionalized force (Fn) vs. deployment angle (Ψ) for various natural deployment angles (Ψ0) with a zoomed-in view highlighting the detailed behavior below. c Plots of non-dimensionalized force (Fn) vs. non-dimensionalized displacement (Dn) for various natural deployment angles (Ψ0) with a zoomed-in view highlighting the detailed behavior below. d 3D CAD model of a bellows model composed of four repeating units with one corner highlighted (top), and load vs. displacement curves from the analytical model and experimental results (bottom). e 3D DIC results of the four-unit bellow model captured at four different stages of deployment corresponding to points marked in (d).
