报告简介To effectively describe the multi-phase interactions within a multi-scale and multi-physics framework, a robust spatial discretiaztion method is a necessity. Over the last twenty years, the Material Point Method (MPM, http://en.wikipedia.org/wiki/Material_Point_Method), which is a spatial discretization extension from Computational Fluid Dynamics to Computational Solid Dynamics, has evolved with applications to different areas in Simulation-Based Engineering Science (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 of modern engineering problems, with a concurrent link between the Dissipative Particle Dynamics (DPD) method and the MPM, and a hierarchical bridge from Molecular Dynamics (MD) to DPD. It appears that the DPD forces can be effectively coarse-grained using the MPM background grid, and that the concurrent link between the MPM and DPD enables near-seamless integration of constitutive modeling at the continuum level with force-based modeling at the mesoparticle level. Recent advances with representative examples on modeling and simulation of structural responses to extreme loading conditions will be presented in the seminar to demonstrate the potential of SBES.

报告人简介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 nearly 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 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.
