Abstract: Additive manufacturing is a transformative set of technologies that are increasingly being used for aviation applications. However, persistent challenges regarding throughput, reproducibility, reliability, and properties of the printed parts seriously impact qualification and certification (Q&C). Computational Materials for Qualification and Certification (CM4QC) is a tightly focused collaboration of aviation OEMs, research and regulatory government agencies, and universities that is working to develop a strategy for broadly incorporating computational approaches into the aviation AM Q&C process. Critical aspects include metrics for evaluating the maturity level of AM-targeted simulations, model uncertainty quantification, model validation, and performance risk assessment. The CM4QC strategy will be discussed with particular focus on the importance of rigorous model validation. Examples of model validation will be taken from the NIST-led Additive Manufacturing Benchmark Series (AM Bench), which provides rigorous measurement test data for validating AM simulations for a broad range of AM technologies and material systems.  

About Lyle Levine: Dr. Lyle Levine is a physicist in the Material Measurement Laboratory (MML) of the National Institute of Standards and Technology (NIST), where he leads most of NIST’s materials research in additive manufacturing (AM) of metals. Dr. Levine has founded and led numerous multiple-institution research and development efforts. For AM, he founded and co-leads AM Bench, an international organization that provides a challenge problem series and AM benchmark measurement data for the AM community. With measurement partners from 10 NIST divisions and 20 external organizations, AM Bench is the world’s leading provider of AM benchmark data. Dr. Levine also led the experimental validation effort for ExaAM, the DOE-funded Exascale Computing Project’s effort to develop codes for simulating AM processes on the first generation of exascale high-performance computing platforms that are now coming online.  In addition, Dr. Levine is a founding member of Computational Materials for Qualification and Certification (CM4QC), which includes representatives from major US aerospace companies, government agencies, and universities working to establish a focused and coordinated path for the development of computational materials-enabled qualification and certification of AM materials and components for aviation applications. Dr. Levine is the Lead Editor and also leads the CM4QC working group aimed at transitioning basic research into engineering applications.  In addition to his work on AM, Dr. Levine founded the continuing Dislocations Conference Series and is highly active in synchrotron X-ray science, where he develops and uses new diffraction, scattering, and imaging measurement methods for studying material microstructures in situ and in operando.  Dr. Levine has authored and co-authored more than 160 papers, served on numerous advisory and review boards, received numerous awards, and is a frequent invited speaker both domestically and abroad. He is an adjunct professor of Mechanical Engineering at the University of Southern California and Northwestern University.
