Replying to the invitation of Professor Yunqing Zhang of National Research Center for CAD, Mechanical School of Science and Technology, Dr. Zhen Luo of University of Technology, Sydney visited Huazhong university of science and technology on July 8. In the afternoon, Dr. Zhen Luo gave an academic report named “Design of functionally-graded cellular composites using a multi-scale topology optimization method” in National Research Center for CAD.
Dr. Zhen Luo introduced some advanced topics in the field of cellular composites and topology optimization methods including homogenization, solid isotropic material penalization methods (SIMP), evolutionary structural optimization methods, level set methods and so on. This presentation was focused on integrating engineering design of functionally-graded materials and structures for cellular solids using topology optimization. A new method has been developed by Dr. Zhen Luo to solve the design problem of the macro structure and micro-structured materials named multi-scale topological optimization method. The first scale optimization is called macro-structural design using the SIMP method to describe the hierarchical structural layout with layer-wise intermediate densities, and the second scale is an inversed material design process of micro-structures by combining the numerical homogenization approach into a powerful parametric level set method. Several numerical examples have been given to show the characteristics of the proposed engineering design methodology. At last, Dr. Zhen Luo discussed some related topics of topology optimization with the staffs and students who attended the presentation.
