Zhen Chen简历:

Dr. Zhen Chen is a C.W. LaPierre Professor in the College of Engineering at the University of Missouri (MU). His research area is in Computation Mechanics with a recent focus on multi-scale modeling and simulation of the multi-physical phenomena involved in structural failure subjected to extreme loading conditions. Before joining MU in 1995, Dr. Chen was a design engineer in Shanghai Medical Electronics Factory, a professional staff member in the Applied Mechanics Division at New Mexico Engineering Research Institute as well as in the Department for the Waste Isolation Pilot Project/Performance Analysis Code Development at Sandia National Laboratories. Dr. Chen has more than 300 publications based on funded research projects. He serves on advisory editorial board of the International Journal for Multiscale Computational Engineering, board of editors of CMES: Computer Modeling in Engineering & Sciences, editorial board of Computational Particle Mechanics, and advisory board of International Journal of Damage Mechanics, respectively. Among his honors and awards are the Fellow of ASME, the Fellow of the ICACM, the Yangtze visiting professor and Qianren-Plan visiting professor appointed by the Ministry of Education in China, the Faculty Research Award in the College of Engineering at MU, the Outstanding Youth Award (Oversea) from the National Natural Science Foundation of China, and the NSF-CAREER Award.  He received his Ph.D. degree in solid and computational mechanics from the University of New Mexico in 1989.

报告摘要:

Simulation-based Engineering Science (SBES), which allows detailed parametric studies and complements experiments, is playing an increasingly important role in evaluating extreme loading responses. If the fidelity of SBES is assured, the number of experiments could be reduced for verification and improvement of new designs. However, how to effectively handle the multi-phase (solid-fluid-gas) interactions involved at different scales remains to be a challenging task in spatial discretizaiton, and even more daunting when the evolution of material failure occurs under blast and fragmentation. Since its first journal paper was published in 1994 , the Material Point Method (MPM), which is a spatial discretization extension from Computational Fluid Dynamics to Computational Solid Dynamics, has evolved with applications to different areas in SBES as well as in the movie industry . Recently, a particle-based computer test-bed is being developed for multi-scale and multi-physics modeling and simulation to advance SBES, with a focus on the multi-phase interactions involving failure evolution such as model-based simulation of energetic composite responses and additive manufacturing . In this seminar series, the recent research results will be presented and future directions will be discussed to promote integrated research, education and economic development via interdisciplinary team efforts.
