From: Superstretchable, yet stiff, fatigue-resistant ligament-like elastomers

a Ashby plot of “Young’s modulus” and "λ" of this work and other stretchable materials (λ > 3,000%, λ = L/L0, L0 is the initial length between the clamps, L is total length between the clamps). b Ashby plot of “Toughness” and "λ" of this work and other stretchable materials (λ > 3,000%).
