Most of engineering materials have their hierarchical structures at different length scales. The structure in each length scale influences one another and eventually the macroscale properties of the materials. In order to understand and predict macroscale properties of materials, it is important to analyze the characteristics and bridging of different length scale structures. To this end, multiscale modeling and analyses have been developed for different materials such as composites, metals, biomaterials, etc. This presentation focuses on a generalized multiscale analysis model developed for various composites materials as well as biomaterials. Recently, new failure criteria were proposed for fibrous composite materials. The criteria are based on distinctive failure mechanisms of the constituent materials such as fiber failure, matrix cracking and fiber/matrix interface debonding. The criteria use the stress and strain occurring in the fiber and matrix materials. Human bone was also analyzed using a similar multiscale approach.
Dr. Kwon is Distinguished Professor in the Mechanical and Aerospace Engineering Department of Naval Postgraduate School (NPS) in Monterey, California, USA. He also serves as Director of Materials Research Center at NPS, and was a past Chair of the department. Previously, he was also Professor and Chair of the Department of Mechanical Engineering and Energy Processes of Southern Illinois University Carbondale (SIUC). He received his Ph.D. degree from Rice University, and B.S. degree from Seoul National University, all in mechanical engineering. Before joining NPS, he was Assistant Professor at the University of Missouri-Rolla. His research interests are multiscale, multiphysics and multidisciplinary problems in engineering and sciences. In order to address those problems, he developed new analytical and computational techniques, and also designed new experimental apparatus. He has published extensively in those topics. He wrote the textbook, Finite Element Method using MATLAB which was also translated into a Greek book. He also authored a book titled Multiscale and Multiphysics Modeling: Techniques and Applications. He has contributed chapters in multiple books and encyclopedias. He edited a book titled “Multiscale Modeling and Simulation of Composite Materials and Structures” published by Springer. Prof. Kwon received many awards including the Cedric K. Ferguson Medal from Society of Petroleum Engineers, Menneken Faculty Awards for Outstanding Research, Excellent Research Award from American Orthopedic Society of Sports Medicines, Outstanding Instruction and Research Awards, ASME Dedicated Service Award, ASME PVPD Outstanding Service Award, ASME Board of Governors Award, National Dean's List, etc. He is a fellow of American Society of Mechanical Engineers. Dr. Kwon is the technical editor for ASME Transactional, Journal of Pressure Vessel Technology, as well as Multiscale and Multidisciplinary Modeling, Experiments and Design published by Springer Nature. He is a past ASME PVP Division Chair.
