| Abstract Scope |
Computational materials-based approaches that provide greater understanding of process intensive manufacturing processes (e.g., additive manufacturing) and the performance of the resulting components are emerging as an enabler for more flexible and efficient methods for Qualification and Certification (Q&C). To ensure effective application of such methods, the appropriate regulatory requirements need to be considered, including a common requirement that “test evidence is needed to support analysis.” Motivated by these requirements and opportunities, NASA and the FAA have established the Computational Materials for Qualification and Certification (CM4QC) steering group comprised of representatives from the aviation industry, government regulatory and research organizations, and academia. We will discuss the industry needs and regulatory considerations that motivate this national effort and provide an update on CM4QC’s progress toward development of a roadmap for computational materials approaches for Q&C with focus on gaps in testing and characterization data needed for developing simulation input and validation. |
