arXiv:2606.07146v1 Announce Type: new Abstract: Physics-informed machine learning is often assessed by curve error, although engineering use depends on downstream decisions: ranking candidates, avoiding infeasible designs and limiting regret. We introduce pinn-gym, an open benchmark for material-conditioned lattice design that couples a transparent reduced-order crush-and-impact oracle with five printable polymer cards, dimensionless force-response targets and a protocol spanning curve fidelity, physical admissibility, top-k retrieval and mass regret. Across per-material, pooled and cross-mate
The proliferation of Physics-Informed Machine Learning models necessitates more robust evaluation mechanisms that move beyond simple curve fitting to assessing real-world engineering utility, making this benchmark timely.
This development proposes a critical shift in how physics-informed AI models are evaluated, emphasizing practical decision-making and quantifiable engineering performance over purely theoretical accuracy, which directly impacts the reliability and adoption of AI in critical engineering fields.
The introduction of 'pinn-gym' offers a standardized, decision-aware evaluation paradigm, raising the bar for AI model development in material science and potentially accelerating the deployment of trustworthy physics-informed surrogates.
