Mechanical nonlinearity and anisotropy of patterned VSMC sheets. a) Representative Cauchy stress-stretch curve of a monolayer VSMC sheets. b) Max stretch, max stress, tensile modulus at low and high stretch was analyzed based on the stress-stretch results. c) Normalized ratio of the mechanical properties to better quantify anisotropic mechanical behavior. Ratio=1 indicates isotropic behavior. n=3, *, relative to NP (P<0.05), # relative to P (⊥) (P<0.05)
