Distinguished Lecture in Materials

2040 Vision Study and NASA’s TTT Implementation Activities

Featuring Steven M. Arnold, Technical Lead for Multiscale Modeling, Materials and Structures Division, NASA Glenn Research Center

Abstract: Over the last few decades, advances in high-performance computing, new materials characterization methods, and, more recently, an emphasis on integrated computational materials engineering (ICME) and additive manufacturing have been a catalyst for multiscale modeling and simulation-based design of materials and structures in the aerospace industry. As a result, NASA’s Transformational Tools and Technology (TTT) Project sponsored a study (performed by a team led by Pratt & Whitney) to define the potential 25-year future state required for integrated multiscale modeling of materials and systems (e.g., load-bearing structures) to accelerate the pace and reduce the expense of innovation in future aerospace and aeronautical systems.  This talk will briefly review the findings of this 2040 Vision study (e.g., the 2040 vision state; the required interdependent core technical work areas, Key Element (KE); associated critical gaps and actions to close those gaps; and major recommendations) and discuss NASA’s implementation activities within the TTT project. The study, NASA CR 2018- 219771, envisions the development of a cyber-physical-social ecosystem comprised of experimentally verified and validated computational models, tools, and techniques, along with the associated digital tapestry, that impacts the entire supply chain to enable cost-effective, rapid, and revolutionary design of fit-for-purpose materials, components, and systems.  Although the vision focused on aeronautics and space applications, it is believed that other engineering communities (e.g., automotive, biomedical, etc.) can benefit as well from the proposed framework with only minor modifications. Finally, it is TTT’s hope and desire that this vision provides the strategic guidance to both public and private research and development decision makers to make the proposed 2040 vision state a reality and thereby provide a significant advancement in the United States global competitiveness.

Bio: Steven M. Arnold is currently the Technical Lead for Multiscale Modeling within the Materials and Structures Division at NASA Glenn Research Center with over 35 years of experience. He also is the Technical Lead for the Materials and Structures Discipline within the Transformative Tools and Technology (TTT) project. Dr. Arnold conducts research involving theoretical and experimental investigations of structural material behavior of advanced aircraft propulsion systems and spacecraft structures. He has over 475 technical publications, 114 of which are journal publications and is a co-author of two books on micromechanics of composites, i.e., “Micromechanics of Composite Materials: A Generalized Multiscale Analysis Approach” 2013 and “Practical Micromechanics of Composite Materials” 2021. 

He received NASA’s Exceptional Service Medal in 2019, NASA’s Exceptional Technology Achievement Medal in 2014 and the NASA Glenn Abe Silverstein outstanding research award in 2004.  He also was awarded the ASC/DEStech Award in Composites for 2015.  He is, on the NAFEMS Americas Steering Committee; an ASM International Fellow (class of 2013), Chairs the Core and Emerging Technologies Council for ASM, and participates on the Materials Data Information & Data Analytic Technical Committee; a member of AIAA and Chairs the Materials Technical Committee and ICME working group, and participates on the Digital Engineering Integration Committee (DEIC) in both the digital twin and digital thread subcommittees; and co-founder and chairman of the Material Data Management Consortium (MDMC).
