Dr. Steven Arnold (NASA Glenn)














Dr. Steven M. Arnold is the Technical Lead for Multiscale Modeling within the Materials and Structures Division at NASA Glenn Research Center with over 30 years of experience. 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 the development and distribution of numerous computational tools: the most notable being the award winning micromechanics analysis code MAC/GMC; a nonlinear hardening, multi-mechanism, potential based, unified viscoelastoplastic model (GVIPS) and model parameter optimization code, COMPARE.  He hasover 375 technical publications, 104 of which are journal publications and is a co-author of the book, “Micromechanics of Composite Materials: A Generalized Multiscale Analysis Approach”.  He is an ASM International Fellow, active in AIAA materials TC, author of two US Patents, the 2015 ASC/DEStech Award in Composites recipient, and co-founder and chairman of the Material Data Management Consortium (MDMC) and director of MACE, NASA Glenn’s Multiscale Analysis Center of Excellence.
