Join us in welcoming Dr. Chuck Zhang to the ISE/ME graduate seminar. Dr. Zhang will present his seminar titled"Applications of AI to Advanced Materials and Structures Manufacturing."
This seminar will highlight two research studies on applications of AI to manufacturing of advanced materials and structures. The first one involves personalized heart surgery planning and optimization with integration of advanced materials design, additive manufacturing, and machine learning techniques. In this study, a meta-material design approach together with ML was first developed to create a structure that can mimic mechanical behavior of human aortic valves. The tissue-mimicking heart valves were then fabricated using a multi-material 3D printing process. The 3D printed heart valves can be used for AI-driven pre-surgery planning of heart disease treatment and intervention. The second study focuses on the development of a physics-inform ML model for quality prediction of adhesive joints in composite structures. In this work, a novel framework of Physics-Informed Neural Ordinary differential equation with Heterogeneous control Input (PINOHI) is created, which links the heterogeneous manufacturing parameters to the final bonding quality of composite joints. The model structure is heavily motivated by engineering knowledge, with incorporation of a calibrated mathematical physics model into the Neural ODE framework, which can significantly reduce the number of data samples required from costly experiments while maintaining high prediction accuracy.
Dr. Chuck Zhang is a Eugene C. Gwaltney, Jr. Chair and Professor in the H. Milton Stewart School of Industrial & Systems Engineering at Georgia Institute of Technology. Currently on leave from Georgia Tech, he serves as a Program Director for the Regional Innovation Engines (RIE) Program in the Directorate for Technology, Innovation and Partnerships (TIP) at National Science Foundation. He also served as the Founding Director of the three-university NSF Industry/University Cooperative Research Center (IUCRC) for Composite and Hybrid Materials Interfacing (CHMI).
Dr. Chuck Zhang received his Ph.D. degree in Industrial Engineering from the University of Iowa.
