Extended Data Fig. 3: Comparison of the full-field σ22 predictions and FE ground truth (indicated in [MPa]) for four generated structures (a-d) without conditioning.

Fields are shown in the Eulerian frame for all eleven strain steps, including the corresponding relative L2-error. *The relative L2-error at ε = 0.2% is numerically inflated due to the small magnitude of the stress field and is hence not truly indicative (but included for completeness).
