Material (shared — Zocher / SLS)

Material A of Zocher, Groves and Allen (1997): $E_0=0.5\,\mathrm{MPa}$, $E_\infty=0.1\,\mathrm{MPa}$, $\tau_\sigma=1$ t.u., $\tau_\varepsilon=\tau_\sigma E_0/E_\infty$, $\nu=0.3$.

• ref_zocher_params.csv
• ref_zocher_J_R.csv — analytical $J(t)$ and $R(t)$

The $\eta_n$, $q_n$ algorithm under unit stress must recover $J(t)$ independently of the mesh.
