Prof. Xunzhong Guo is Professor of metal forming and plasticity, and Leader of the institute of advanced metal forming technologies, College of Material Science and Technology, Nanjing University of Aeronautics and Astronautics (NUAA), Nanjing, China. The research interests of him are flexible forming technologies (such as 3D-free bending technology, incremental forming technology, spinning forming technology, hydroforming, and multi-point forming technology); finite element modeling and simulation of sheet and tube metal forming processes; materials characterization and microstructure evolution; crystal plasticity finite element modeling (CPFEM); multi-scale mechanics of materials; and formability improvement and prediction. His research group has achieved significant results in the aforementioned research era, successfully designed and manufactured the first flexible free bending equipment in China, and successfully manufactured some thin-walled complex shaped components used in some critical engineering such as aerospace, nuclear, railway, and automotive applications. Meantime, his research group has carried out outstanding research on key technologies for process simulation optimization and defects control. He has published more than 40 journal papers in high-impact international journals, and he possesses around 20 patents. He led the development of internal high-pressure forming series equipment, tube forming performance evaluation equipment, sheet forming performance testing equipment, incremental sheet metal forming equipment, and three-dimensional free bending forming equipment.
