摘要： 
This seminar will focus on a hierarchical multi-scale topology optimization method for the design of integrated materials and structures by taking advantage of both cellular composites and functionally graded materials. The topology optimization involves two scales: firstly, macrostructural design using SIMP to generate an overall multilayered layout with free material distribution involving intermediate densities; and secondly, microstructural design to produce periodic cellular composite for each layer, by integrating the numerical homogenization into a level set approach. Thus, the cellular composites will be characterized by variation in microstructures and the corresponding changes of properties over layers. The proposed method can generate new artificial composites similar to functionally graded materials but layer-based, to achieve multifunctional properties for energy absorption, anti-impact, thermal isolation.

Dr Zhen Luo received his PhD in mechanical engineering from National Engineering Research Centre for CAD, Huazhong University of Science & Technology in 2005. After that, he worked as a research fellow respectively at Chinese University of Hong Kong, University of Sydney, and University of New South Wales for 6 years. He joined University of Technology, Sydney (UTS) in 2011 as a Chancellor’s Research Fellow, and has been with UTS as Senior Lecturer since October 2012.
Dr Luo’s research focuses on structural optimization of topology and shape, computational mechanics, uncertainty analysis and optimization, sampling and surrogate modelling, and computational design of micro- and nanostructured composites. He is the group leader of “Engineering Computations and Optimization” (Eco) at UTS mechanical engineering, which is hosting 3 PhD research students, and 1 postdoc fellow, and 1 visiting scholar. He has published over 60 research journal papers including 43 ISI-JCR Q1 journal papers, with h-index 18, and over 700 citations in Scopus.
He has been a Core Investigator for several competitive research projects, including Australian Research Council - Discovery Project (ARC DP), National Natural-Science-Foundation of China (NSFC) projects, and Australian AutoCRC Projects. He has been a mini-symposium organizer, technical chair, and organizing committee member for several main stream conferences, including WCCM2014 (Spain), ECCOMAS2016 (Greece), and WCCM2016 (Korean). He holds several professional memberships, like International Association of Computational Mechanics (IACM), and International Society for Structural and Multidisciplinary Optimization (ISSMO).
