| # Start here: T2 multiaxial OOD research release |
|
|
| This package is designed for a collaborator or AI agent to continue the |
| research without reconstructing the project history. |
|
|
| ## Read in this order |
|
|
| 1. `README.md` for the complete dataset overview. |
| 2. `artifacts/t2_multiaxial_ood_v2/QUALITY_REPORT.md` for physics validation. |
| 3. `artifacts/t2_multiaxial_ood_v2/model_metrics.json` for all model results. |
| 4. `models/t2_multiaxial_ood_v2/README.md` before loading checkpoints. |
| 5. `docs/T2_MULTIAXIAL_RESEARCH_MEMO.md` for the manuscript argument and next |
| method contribution. |
| 6. `T2_V2_REPRODUCE.md` for exact commands. |
|
|
| ## What may be claimed now |
|
|
| - The data generation and physical audits passed. |
| - History-aware models strongly outperform a history-blind control on ID data. |
| - Path-family OOD is substantially harder than the frozen parameter-OOD test. |
| - Selected hard physical constraints remove corresponding state violations. |
| - A state-output physics GRU did not transfer reliably to the structural gate. |
| - A physics-embedded neural stress integrator reduced path-OOD RMSE to 0.0237 |
| MPa and passed both frozen structural gates; the severe case recorded one |
| trust-region fallback at complete unloading. |
|
|
| ## What may not be claimed now |
|
|
| - production-ready neural constitutive modeling; |
| - general 3D AgentFEM learned-material integration; |
| - experimental-material accuracy; |
| - transfer of the white-box result to unknown or misspecified material laws; |
| - general structural convergence without the recorded global fallback; |
| - end-to-end acceleration in the current Python structural demonstrator. |
|
|
| ## Highest-value continuation |
|
|
| Develop a gray-box evolution model in which the embedded constitutive skeleton |
| is deliberately incomplete and the network learns missing evolution terms or |
| latent internal variables. Add a verified consistent tangent, 2D/3D gates and |
| experimental or high-fidelity microstructural data. Retain the current splits |
| and structural gates unchanged so improvement is measurable. |
