报告简介：

There is an increasingly urgent need to improve product quality, reduce product cost, enhance productivity and shorten time-to-market in metal forming industries. In these demands, the improvement and control of product quality is the first and most critical. Regarding the product quality from defect-free perspective, flow-induced and stress-induced defects are two main deformation defects in forming processes. The former is caused by the irrational flow pattern, while the latter is generated by the working stress exceeding the strength limit of materials. The most common defect of the latter is the ductile fracture occurring in forming process. In this talk, the flow-induced defects are extensively articulated, discussed, and analyzed in terms of flow behavior, formation mechanism, and avoidance methods in multiscaled deformation processes from macro-, meso- to microscale by using experiments and simulations. The simulation-enabled methodology and feature-based method are proposed to aid the design of defect-free metal formed part, forming process, sequence, and die structure. Through case studies, the presented design framework and the feature-based approach for defect-free forming sequence design are validated and verified by both experiment and simulation. The prediction and analysis of fracture behaviors and occurrence in macro- and micro-scaled deformation are given. Using the physical experiments in multiscaled deformation, the simulation-enabled methodologies are corroborated by experiments, and thus providean efficient tool for metal forming product development in industries.

报告人简介：

Dr. Mingwang Fu is a professor in the Department of Mechanical Engineering, The Hong Kong Polytechnic University. He received his B.Eng and M.Eng degrees from the Northwestern Polytechnical University, China, and PhD from the National University of Singapore.Before he went to Singapore for his career development, he had worked in China as a professor and conducted many projects funded by governmental agencies and industries. In 1997, he joined the Singapore Institute of Manufacturing Technology as a Senior Research Engineer. In Aug 2006, he joined the Hong Kong Polytechnic University as a faculty member.Prof Fu is quite active in exploring advancedmaterials processing, numerical modeling and simulation, product design and development, and micro-mechanics by using state-of-the-art technologies to seek for the epistemological understanding of the science behind these explorations, advancing knowledge in these areas, and successfully addressing a plethora of challenges and bottleneck issues the explorations face. His research findings have benefited the development of the technologies in the above-described arenas and academic disciplines, and led to about 180 SCI journal papers and a number of monographs published top-notched publishers including Marcel Dekker (New York), Springer-Verlag London Ltd, CRC Press, Taylor & Francis Group, andElsevier. Prof Fu is also sitting in the editorial board of a number of prestigious SCI journals, which include Int. J. of Plasticity, Materials and Design, Int. J. of Damage Mechanics, Int. J. of Adv. Manu. Tech., and Chinese J. of Mechanical Engineering, etc. He is often invited to give keynote or plenary talk in many well-known international conferences in different countries including Germany, Russia, United Kingdom, USA, Australia etc. and talk/lecture in some top universities worldwide.
