Stewart, Calvin

Biography

Calvin M. Stewart is the College of Engineering Innovation Scholar and Associate Professor in the Department of Aerospace and Mechanical Engineering and Department of Materials Science and Engineering at the Ohio State University. He obtained a BS, MS, and PhD in Mechanical Engineering at the University of Central Florida in 2008, 2009, and 2013 respectively. 

Dr. Stewart directs Materials at Extremes which focuses on the advanced manufacturing, mechanical testing, and theoretical mechanics of materials subject to thermal, mechanical, and chemical extremes. Within the gamut of extremes: creep, fatigue, thermomechanical fatigue, and fracture are key focus areas.

Current research involves the low-cost additive manufacturing of superalloys and refractory alloys for extreme environments, development of accelerated, parallelized, and miniaturized testing protocols for new materials qualification, and the development of probabilistic, machine learning, and advanced models for the mechanics of material in extreme environments.

Dr. Stewart has authored over 80 articles and has generated over $11M in research expenditure through grants/contracts with the U.S. Department of Energy, National Nuclear Security Administration, National Energy Technology Laboratory, Office of Nuclear Energy, Nuclear Regulatory Commission, Honeywell FM&T, Air Force Research Lab, among others.
