The excess shear modulus $G-\mathrm{\Delta }G*$ scales linearly with the shear stress $\tilde{\sigma }$ in 2D spring networks. We find a collapse when rescaling $G-\mathrm{\Delta }G*$ by the critical shear strain $\gamma *$. The black dashed line corresponds to the prefactor of 3, as predicted by Eq. 13. (Inset) The excess shear modulus $G-\mathrm{\Delta }G*$ scales linearly with the isotropic stress $-p$, and we obtain a collapse when rescaling the latter by $b/{\ell }_0*$. The black dashed line is the prediction according to Eq. 13.
