Dr. Steven M. Arnold

Technical Lead, Multiscale Multiphysics Modeling

NASA Glenn Research Center, USA

Dr. Steven M. Arnold is the Technical Lead for Multiscale Modeling within the Materials and Structures Division at NASA Glenn Research Center with over 34 years of experience. He also is the Technical Lead for Multiscale Modeling within the Materials and Structures Division and Discipline Lead for Materials and Structures 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. His primary emphasis is on the development of advanced high temperature viscoelastoplastic deformation and damage constitutive models, and the associated multi-scale design and analysis computational tools required to make these models accessible to the engineering community.

Dr. Arnold's research activities have resulted in over 475 technical publications, 114 of which are journal publications, two US Patents, and is a co-author of the books, “Micromechanics of Composite Materials: A Generalized Multiscale Analysis Approach” and “Practical Micromechanics of Composites”. He is a member of the NAFEMS Simulation Data Management Working Group; an ASM International Fellow; active in AIAA’s Materials Technical Committee, ICME working group, and Digital Engineering Integration Committee (DEIC); and co-founder and chairman of the Material Data Management Consortium (MDMC). He also has received the 2014 NASA Exceptional Technology Achievement Medal, the 2015 ASC/DEStech Award in Composites, the 2019 NASA Exceptional Service Medal.
