Figure 1:

Variation of the shear elastic modulus $G_{\text{s}}$ of the neo-Hookean (NH) and Yeoh (YE) laws, normalized with the shear elastic modulus of Skalak law $\left(G_{\text{s}}^{\text{SK}}\right)$, with respect to the principal extension ratio ${\lambda }_1$, so that all constitutive laws produce the same principal tension ${\text{T}}_1$.
