Fig 5. Elastic energy of shallow elliptical scaffolds with isotropic curvature (ρ_a = ρ_b = ρ; r_a ∕ ρ ≪ 1; r_b ∕ ρ ≪ 1) as a function of the normalized distance between scaffolds centers, for various values of the aspect ratio r_a/r_b.

In all calculations$r=\sqrt{r_a{r}_b}=0.2\rho$. The curves are calculated for parallel orientation of the scaffold long axes, which corresponds to lowest energy at each distance. The parameters are as in Fig. 2.
