Armour College of Engineering's Mechanical, Materials, and Aerospace Engineering Department will welcome Dr. Caizhi Zhou, Roberta and G. Robert Couch Assistant Professor in the Department of Materials Science and Engineering at Missouri University of Science and Technology, on Friday, April 19th, to present his lecture, Multiscale Modeling of Deformation in Advanced Metallic Materials: From Atomic-scale to Macro-scale.


Advanced metallic structural materials, such as metallic nanolayered composites, heterogeneous and gradient materials, have drawn increased attention in the past decade because of their ultrahigh strength, increased ductility and elevated fracture toughness. Fundamental barriers must be resolved to manufacture such advanced metallic materials in bulk form and at reduced cost. Significant research has been conducted in recent years to understand the underlying mechanisms that control the mechanical behavior of these advanced materials. Both experiments and modeling have revealed that as microstructure length-scales are reduced, interfaces, such as grain boundaries and phase boundaries, become crucial in determining the mechanical behavior of those materials. Through the development of computer resources and novel experimental methods, macroscopic and phenomenological descriptions of mechanical behaviors are being substituted by multiscale approaches rooted in deeper understanding of microstructure- and defect-level processes during the deformation. Challenges remain in developing models with truly predictive capability in applications to nanostructured materials. This talk will review various modeling tools at different length scales and present a new hierarchical multiscale modeling framework to study mechanical behavior of advanced metallic structural materials and provide a scientific basis for design and processing advanced materials with superior properties.


Dr. Caizhi Zhou received his B.S. degree in Metallic Materials Science and Engineering, at Tianjin University, China, in 2003, and M.S. degree in Materials Processing Engineering, at the same University in 2006.  He earned his Ph.D. degree in Materials Science and Engineering at Iowa State University in 2010, with graduate research excellent award. He then worked at Los Alamos National Laboratory as a postdoctoral researcher from 2011 to 2012. He joined Missouri University of Science and Technology in the spring of 2013 as Roberta and G. Robert Couch Assistant Professor. Dr. Zhou’s research involves building high-throughput computational modeling methods that aim to uncover and understand key deformation mechanisms in structural materials, to model their predominant defect interactions and simulate manufacturing processes in order to design pathways for target microstructures.

He has won National Science Foundation (NSF) CAREER Award for his work on multiscale modeling of the interface-mediated deformation in layered composites. He has published over 40 articles on peer-reviewed journals, including Physical Reviews Letters, Scientific Reports, Acta Materialia, Journal of the Mechanics and Physics of Solids, Scripta Materialia, International Journal of Plasticity. He has been an invited reviewer for more than 15 scientific journals and presented 10 invited talks at international conferences. Because of his competent leadership, he has been awarded the Minerals, Metals & Materials Society (TMS) TMS Young Leader Professional Development award in 2015.
