(A–C) Predicted and observed behavior of the bulk modulus discontinuity $\mathrm{\Delta }B$ for (A) 2D spring networks for different values of the coordination number $z$, (B) the 2D vertex model for different values of the area rigidity $k_A$, and (C) the 3D Voronoi model for different values of the volume rigidity $k_V$. Blue circles indicate simulations and the red curves indicate predictions without fit parameters based on Eq. 9. In A, the black dashed curve is computed using values for transition point ${\ell }_0*$ and geometric scaling coefficient $a_{\ell }$ directly measured for each value of $z$, while for the red line we used the scaling relations from Table 1.
