Extended Data Fig. 4: Analytical and FEA results of typical chiral models.
From: Large recoverable elastic energy in chiral metamaterials via twist buckling
The four panels show the generalized force F1rod/Fs, generalized energy U1rod/Us, twisting rotation angle of the chiral unit θ, and generalized stress in rod σv/Es versus global equivalent strain ε = s/h0. All panels share the same legends as panel 1. In these models, R1 = R2, r = 1.5 mm.
