Figure 4. Self-similar network designs for multistage non-linear mechanical response and extreme stretchability.

(a) Schematic illustration of a wavy network with a 2nd order self-similar architecture consisting of horseshoe building blocks. (b) Stress–strain responses (with the stress in logarithmic scale) for wavy networks constructed using 1st and 2nd order designs. For strains between 0–60% and 70–145%, results appear in linear scale in c and d for the 2nd order design. (e) Deformation configurations at four different levels of stretching with associated maximum principle strain.
