Abstract
The multiscale solid mechanics tools are the major keys for understanding, designing and achieving the new nanomaterials. The ability to create structural materials of high yield strength and yet high ductility has been a dream for materials scientists for a long time. We summarize the recent developments of the advanced nanomaterials with exceptional mechanical properties. The basic concept of surface nanocrystallization of materials will be presented. The computational models successfully simulate the enhanced ductility and strength and provide valuable information about the failure mechanisms of the nanostructured material. Based on the new concepts developed for toughening the high strength materials, different new categories of nanomaterials have been realized. The development of materials and structures with nano-, micro- and macro-scale functional gradients for generating different toughening mechanisms using the non localization approach will be presented. The applications in different industrial sectors (automotive, biomedical, civil structure, aerospace, energy) will be presented.

About the speaker
Prof. J.LU commenced his undergraduate education in 1978 at Peking University where he was selected for a national scholarship for overseas study in 1979. He obtained the Dip. Ing., Master degree and Doctoral degree from UTC(Compiegne) France in 1984 and 1986 respectively. He obtained the Habilitation from the University Paris 6 in 1993. In 1994, he was appointed as Professor, Head of Department of Mechanical Systems Engineering and Director of Mechanical Systems and Concurrent Engineering Laboratory jointly supported by the French Ministry of Education and CNRS at the University of Technology of Troyes, France. In 2005, he was appointed as Chair Professor and Head of Department of Mechanical Engineering at The Hong Kong Polytechnic University. Since September 2010, he has been appointed as Chair Professor and Dean of College of Science and Engineering at City University of Hong Kong. His research interests are: mechanics of advanced structural materials, experimental mechanics and residual stress. He has published more than 200 SCI journal papers including 21 papers in Science, Nature Materials, PRL, JMPS, Acta Materialia, IJNME. He was elected as a Fellow of the Society for Experimental Mechanics (USA) and nominated by the French Government in 2006 in the Order of National Merit (Knight).
