Talk Title: Generative Manufacturing: AI + IGA, Digital Twins and Reduced Order Modeling for Applications in Additive Manufacturing
Abstract: Abstract: Generative manufacturing applies the power of artificial intelligence (AI) to generate and execute optimal solutions given customer-defined constraints and parameters, such as functional specifications, cost, and lead time, by exploring vast combinations of design and production alternatives based on material and process availability. In this talk, I will present our latest research on combining AI with isogeometric analysis (IGA) for applications in additive manufacturing (AM). It includes a machine learning (ML) framework for inverse design and manufacturing of self-assembling fiber-reinforced composites in 4D printing, IGA-based topology optimization for AM of heat exchangers, as well as data-driven residual deformation prediction to enhance metal component printability and lattice support structure design in the laser powder bed fusion (LPBF) AM process. By speeding up geometry distortion predictions from several hours to mere seconds, our model can be deployed to prevent generation of infeasible designs. Our on-going efforts also include developing digital twins to enable rapid prediction of stress-induced build failures in LPBF manufacturing using dynamic neural surrogates, where reduced order modeling is a key technique to efficiently simulate underlying physics.
Biography: Bio: Jessica Zhang is the George Tallman Ladd and Florence Barrett Ladd Professor of Mechanical Engineering at Carnegie Mellon University, with a courtesy appointment in Biomedical Engineering. She earned her B.Eng. in Automotive Engineering and M.Eng. in Engineering Mechanics from Tsinghua University, and her M.Eng. in Aerospace Engineering and Ph.D. in Computational Engineering and Sciences from The University of Texas at Austin. Her research interests include computational geometry, isogeometric analysis, the finite element method, data-driven simulations, and image processing, with a strong focus on their applications in computational biomedicine and engineering. Zhang has co-authored over 240 publications in peer-reviewed journals and conference proceedings and is the author of the book Geometric Modeling and Mesh Generation from Scanned Images (CRC Press). Her work spans both theoretical development and practical applications, contributing significantly to advancements in both fields. She is a Fellow of prominent societies, including ASME, SIAM, IACM, USACM, IAMBE, AIMBE, SMA, IMR and ELATES at Drexel, highlighting her distinguished reputation in the field. Currently, she serves as the Editor-in-Chief of Engineering with Computers, further establishing her leadership in computational science and engineering research. Zhang has received numerous awards, including two recent major recognitions: 2025 ASME Van C. Mow Medal for her meritorious contributions to the field of bioengineering and 2025 AWM-SIAM Sonia Kovalevsky Lecture Award for her achievements in applied and computational mathematics.
