Kinematics of a single-layer Yoshimura-ori structure with virtual creases. (A) Introduction of virtual creases to account for facet bending. With virtual creases, panels $\bar{A_{1} P_{1} D_{1}}$ , $\bar{A_{1} D_{1} B_{1}}$ , $\bar{A_{2} D_{2} B_{1}}$ , and $\bar{A_{2} P_{2} D_{2}}$ are treated as rigid during folding. (B) Dihedral angles as functions of the height $h$ .
