Fig. 4. Cold-programming transformable duel-direction panel structures.
A Design and printed sample of a dual-direction shape-morphing structure. B–D The configurations from experiments and FEA simulations with a 50% strain in different directions. E, F Design and printed sample of uni-direction shape morphing structures and the experiment and FEA results with a 50% strain on different directions. G through-hole interlocking assembly of complex 3D architectures with shape-morphing structures. All FEA simulations share the same color map. All scale bar is 1 cm.
