| Abstract Scope |
Materials qualification has long relied on standardized, accredited testing – an approach that assumes global fitness for use. While effective in many cases, this paradigm faces limitations in demanding applications where microstructural characteristics, not just nominal properties, govern performance.
We introduce a structure-centric framework that certifies materials on application-specific fitness, unlocking faster qualification through streamlined approvals and reduced testing. The approach uses structural Representative Volume Elements with rigorous Uncertainty Quantification, providing a portable certificate of fitness that reflects structural fidelity and predictive confidence. Suppliers retain proprietary processing data while sharing only structural and performance information. Purchasers can define target performance and structural statistics through inverse design, enabling tailored processing strategies.
This concept is demonstrated on Cleveland-Cliffs ULTRALUMEŽ PHS, an Advanced High-Strength Steel widely used in automotive structural applications. Confidence is reinforced by physics-informed loss functions that embed constitutive laws and physical constraints, ensuring model fidelity and robust predictions. |
