Male, Han nationality, party member, born in February, 1959. Studying in Britain and America. 1985 received a master's degree from Xi jiaotong university in July, and then worked in the materials research room of Xi thermal research institute of the Ministry of electric power (now the materials research institute of thermal research institute of state power corporation). 199 1 At the beginning of this year, at the invitation and financial support of Keith J. Miller, an internationally renowned professor in the field of material fatigue and fracture, he went to the Institute of Structural Integrity (SIRIUS) of the University of Sheffield in the United Kingdom for a two-year visit study, mainly studying the short-medium crack growth of 3 16L stainless steel under the interaction of creep and fatigue. After that, he studied for doctoral degree and postdoctoral research in the Department of Materials Engineering, Open University of England, and engaged in the study of solder creep failure. 1998 Early in 1998, he went to the Department of Metallurgical Engineering of the University of Utah to do postdoctoral research, mainly engaged in computer simulation of the microstructure of polycrystalline materials and numerical calculation of the strength factor of anisotropic stress field of microcracks, and achieved pioneering research results in microcracks evaluation.

Li Xudong-Details

Returned from the United States in July, 20001,and is now a doctoral supervisor in distinguished professor, Lanzhou University of Technology. He is the leader of the academic echelon and characteristic research direction of Lanzhou University, and took the lead in opening up bilingual teaching for undergraduates in our school. In 2002, as the project leader, he successfully applied for the research project of National Natural Science Foundation. In 2003, as the project leader, he successfully applied for the "National Major Basic Research Pre-research Project", as the Chinese executor, he successfully applied for the Sino-Hungarian International Cooperation Project of Science and Technology of the Ministry of Science and Technology and the Key Scientific Research Project of the Ministry of Education, and successfully applied for the research project of the National Natural Science Foundation in 2005. At present, he is a member of the 4th Council of China Composite Materials Society and the 5th Committee of Mechanical Design Branch of China Mechanical Engineering Society. He is the deputy director of the key laboratory of nonferrous metals and new materials in Gansu Province-the state key laboratory cultivation base built by the provincial office, the vice president of the College of Materials Science and Engineering of Lanzhou University of Technology, and was elected as the standing committee member of the fifth committee of the Federation of Returned Overseas Chinese in Gansu Province.

At present, the main academic achievements can be summarized as follows: 1998, together with American tutors, put forward the concept of "anisotropy of intensity factor of microcrack stress field" and the corresponding numerical calculation method for the first time in the world; Firstly, the physical concept and geometric meaning of "material structural weakness" in the world are summarized in detail, and the characteristic theory of "material structural weakness" is put forward, which provides a new theoretical basis for the integration of "material performance design and material failure behavior prediction". ProDesign, TransMesh and CIPKA software with all intellectual property rights have been developed first in China, which have solved the problems of computer visual simulation of material microstructure, finite element mesh generation and numerical calculation of anisotropic stress field intensity factor respectively. Published many papers in international core journals as the first author.
