Professor Hwang is a major international figure. He is the Director of Institute of Engineering Mechanics at the Tsinghua University and a member of the Chinese Academy of Sciences since 1991. Professor Hwang obtained his B.Sc. degree in civil engineering at the Zhongzheng University in China in 1947 and his postgraduate degree in engineering mechanics at the Tsinghua University in 1952.
Professor Hwang has published six books in Chinese and more than 200 scientific papers in domestic and international periodicals. He has got 16 national and ministry awards for his contributions in mechanics. He has been the principal investigator of 7 national key projects since 1983. His current research fields cover fracture mechanics, transformation plasticity, micromechanics of materials and strain gradient plasticity.
In his talk, Professor Hwang will discuss the recent advances of strain gradient plasticity. A meso-scale continuum theory, namely mechanism-based strain gradient (MSG) plasticity, was proposed by Professor Hwang together with Professor H.J. Gao and Professor Y. Huang, based on dislocation mechanics at the micro-scale. It bridges the gap between continuum plasticity and dislocation mechanics and is intended for applications to materials and structures whose dimension controlling plastic deformation falls roughly within a range from 0.1 to 10 microns. In order to validate this new continuum theory, the results predicted are compared with micron-level experiments. This development will allow us to investigate a range of phenomena that cannot be well addressed by conventional continuum theories, such as near-tip fracture process, the size-dependent of material behavior and strength of thin films. The new structure of crack-tip field is given.
The development of MSG plasticity theory highlights a new era in which advances in modern materials science begin to play an essential part in the founding principles of continuum mechanics.
Members of the Press and interested party are cordially invited to attend.
