专家介绍

Prof Richard Yang joined the School of Computing, Engineering and Mathematics in January 2012 as Associate Professor of Mechanical Engineering and Smart Structures and he was promoted as Professor in 2018. He has been the Leading Director of Academic Programs in Engineering and Industrial Design for a few years. Prior to this, Richard was holding the position of Senior Lecturer in Mechanical Engineering, the School of Engineering, Deakin University (Deakin). Prior to his almost six-year working in Deakin University, he also has worked for a couple of years each in the University of Sydney (USyd) and Korea Advanced Institute of Science and Technology (KAIST) as post-doc research fellow after he finished his PhD in Mechanical Engineering in the University of Hong Kong (HKU) in 2002. He was awarded the Graduate Certificate for Higher Education by Deakin University in 2008.

Prof. Yang has been mainly working in engineering analysis and computational mechanics about 20 years with focusing on characterisation and evaluation of material properties and mechanical behaviours via numerical modelling and simulations as well as experimental analyses. His fields of research include multi-scale modelling of advanced engineering materials and structures, structural health monitoring (SHM) and smart structures, advanced manufacturing and Industry 4.0, metal forming, and metal surface treatment, etc. He has been awarded 1 ARC DP grant in composites, 2 ARC Linkage grants in roll forming of metal sheets, and 4 ARC LIEF grants as well as three competitive overseas research grants, including 1 Beijing Natural Science Foundation Grant (BNSF) on roll forming and 2 National Natural Science Foundation of China Grants (NFSC) on bio-materials from China. In scientific publication, he has published more than 150 journal/conference papers and confidential reports for industrial partners in Mechanical Engineering, Materials Engineering.

报告内容

In this study, graphitised multi-walled carbon nanotubes (GMWCNT) are used to reinforce high impact polystyrene (HIPS) as base material for fabricating nanoparticle reinforced composites with improved material properties – GMWCNT-HIPS. Three weight percentages of nanoparticles in the devised nanocomposites - 1wt%, 3wt% and 5wt% are selected to investigate its weight fraction’s influence on material properties and mechanical behaviours. The nanocomposites are fabricated using moulding injection in lab as standard ASTM samples. These samples are then employed for further mechanical tests including uniaxial tension test and four-point bending test. A microstructural analysis of the samples is conducted to determine the microstructure of GMWCNT-HIPS nanocomposites, in particular for the interfacial zone of nanotube and base material. Meanwhile a finite element analysis is developed and applied for modelling the uniaxial tension and four point bending and conducting a parametric study to guide the adjustment of main control parameters of moulding injection process as a material design tool. The obtained results show that the mechanical properties of final-product materials are influenced by manufacturing processes and controlled by main factors that affect that processes.
