I. Cevdet Noyan has been studying the mechanical response of crystalline materials over various length scales using diffraction since 1978. He was one of the first researchers to combine the theory of micromechanics with that of x-ray and neutron diffraction. He and his group develop x-ray and neutron characterization techniques for non-destructive analysis of structures, with applications spanning suspension bridge cables, integrated circuits, and nanostructures. Noyan and his co-workers also work on the theory of scattering, with particular emphasis on defining the information volumes from which diffraction data are measured, and quantification of the uncertainties associated with such data. 

Research Interests

characterization and modeling of mechanical and micromechanical deformation; residual stress analysis and nondestructive testing; x-ray and neutron diffraction, microdiffraction analysis

Noyan received his B.S. in Metallurgical Engineering from the Middle East Technical University in Ankara, Turkey, in 1978 and his Ph.D. in Materials Science and Engineering from Northwestern University in 1984. His early research work was at IBM, where he received two IBM Outstanding Technical Achievement Awards for research and development of computer and packaging structures, an IBM Research Division Award for research on diffusion barriers, and 11 IBM Invention Plateaus for filed patents. He is also coauthor of the monograph, Residual Stress: Measurement by Diffraction and Interpretation (Materials Research and Engineering).

Prof. Noyan was a member of the organizing committee of the Denver X-ray Conference and co-editor of the Advances in X-Ray Analysis from 1993 through 2019.  He is a fellow of the American Physical Society. He has received the Blackall Machine Tool and Gage Award from the American Society of Mechanical Engineers in 2006, and the Jenkins Lifetime Achievement (2015) and Hanawalt (2019) awards from the International Centre for Diffraction Data”
