Statistical Meso-Mechanics of Damage and Failure: How Microdamage Induces Disaster

Yilong Bai graduated from the University of Science and Technology of China in 1963. Since graduation, he has been associate Professor and Professor at the Institute of Mechanics, Chinese Academy of Sciences. In 1991, he was elected Member of Chinese Academy of Sciences. His research involves in impact dynamics and damage mechanics.  Bai has published over 150 research papers and two monographs (Academic Press, London and Pergamon, Oxford). Mengfen Xia graduated from the Department of Physics, Perking University (China) in 1962. After graduation, he continued his research there as an assistant Professor, associate Professor and Professor in the Department of Physics, Perking University. Since 1989, he is invited as a Visiting Professor by the Institute of Mechanics, Chinese Academy of Sciences. Xia has authored over 100 research papers on plasma physics, nonlinear science, and statistical microdamage mechanics. Fujiu Ke graduated from the Department of Physics, Peking University (China) in 1967. From 1973 to 1987, she was working in the Institute of Physics, Chinese Academy of Sciences. Since 1987, she has been working in the Department of Physics, Beijing University of Aeronautics and Astronautics where she serves as Professor. Her research involves plasma physics, damage mechanics, and molecular simulations.
