Abstract: The field of materials and microstructure design and characterization techniques has progressed significantly in the past two decades. Materials and processing design methodologies effectively utilize the incomplete materials knowledgebase to link final product properties to initial microstructure. Microstructure representation has become a primary vehicle to reach this goal. Characterization techniques that can provide consistent microstructure representation include x-ray, microscopy (SEM, TEM), and tomography. Methodologies that can make the Inverse Materials Design a reality require novel mathematical and computational frameworks and methodologies in addition to experimentally-based knowledge creation to integrate computational-prediction and experimental-validation approaches. This talk will present current advances in multiscale computational materials frameworks based on Microstructure Sensitive Design and statistical homogenization techniques. Microstructure representation and digitization using spectral techniques are at the heart of such methodologies. Application of the present methodologies in thermo-mechanical processing of advanced magnesium alloys, the effect of machining in Al and Titanium alloys and processing of textured silicon solar cells and solid Oxide Fuel Cells are discussed with respect to inverse methodologies.
Bio: Hamid Garmestani is a Professor of Materials Science and Engineering at Georgia Tech and is a Fellow of ASM International and ASME. He got his PhD from Cornell University in 1989, and after serving as a post-doctoral associate at Yale University, he joined FAMU-FSU college of Engineering as an assistant professor in Mechanical Engineering. Dr. Garmestani has had leadership roles in both the American Society of Mechanical Engineers Materials Division and ASM. He has organized more than 30 workshops and symposia in the emerging subject of materials design. He was awarded “Superstar in Research” by FSU-CRC in 2000. He was also the recipient of the Faculty Award for Research from NASA. He is presently funded through DOE, Boeing, NOVELIS and NSF. Dr. Garmestani is a member of the editorial board of International Journal of Plasticity, Journal of Mechanics of Materials, Computers, Materials and Continua and Theoretical and Applied Multi-scale Modeling of Materials. He has developed methodologies in Microstructure Sensitive Design (MSD) framework that address an inverse methodology and innovations in various aspects of processing, structure-property relationships, and simulation-based design of materials.
