Materials at Extremes

ME590 Seminar Speaker Dr. Calvin Stewart


Calvin M. Stewart is the College of Engineering Innovation Scholar and Associate Professor in the Departments of Mechanical and Aerospace Engineering and 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 has authored over 80 articles in these areas and generated over $12M in research expenditure. He is an honored ASTM International Emerging Professional.

Materials are being asked to perform at “extremes” where increased inlet pressures and temperatures in aero gas turbines, the rise of hypersonic flight, and new Generation IV fission and ITER Fusion reactor concepts push the limits of what materials are capable of. There is a need to develop advanced manufacturing techniques to fabricate extreme environment materials, components, and geometries not possible with conventional techniques. To meet this challenge, government, academia, and industry has invested heavily in Additive Manufacturing  technologies and Integrated Computational Materials Engineering (ICME) to achieve “designer” components with processing, structure, properties, and performance designed to survive harsh environments. The quest for new materials requires that we quickly manufacture, qualify, and model the performance of the candidate materials for service.

Materials at Extremes (MATX) focuses on the advanced manufacturing, mechanical testing, and theoretical mechanics of materials subject to thermal, mechanical, and chemical extremes. In this seminar, we will review the ongoing and future research in MATX, and conduct a deep dive into accelerated, parallelized, and miniaturized testing methods for new materials qualification and machine learning for new materials discovery and ICME optimization.
