Brief Introduction of Professor Junzhi Cui
Junzhi Cui,Professor of Academy of Mathematics and Systems Science, CAS, Member of Chinese Academy of Engineering, Member of European Academy of Sciences & Arts. Fields of Interest: Computational Mathematics, Computational Mechanics and Software Engineering.
In 1960's he studied finite element methods and applications. In the spring of 1964, he independently developed first FEM program for plane elastic problem in China, and successfully solved the stress analysis problems of Luijiaxia Dam and others. In 1973 he first discovered that the stress state inside contact bodies depends on the history of imposing loading, and developed a suit of successive linearization methods in terms of incremental theory and variational inequality, and then coded the program, and effectively solved the difficult problems risen in Gongzhui Dam with long vertical cracks and its reinforcement. Since 1980 he was in charge of a series of Nation S/T Key Projects of “6.5”, “7.5”, “8.5”, “9.5” ED Plan, and the key project of CAS, and 8 projects funded by NNSFC, and completed several large-scale software with his colleagues, such as FEPS, BDP, SEFEM and so on. At the same time he set up a suit of software engineering methods to develop the application software of science and technology, such as adaptive organization method of algorithms, configuration model of system and so on. In 1990’s he creatively developed a kind of high-order multi-scale computational methods for predicting the physics and mechanics performance of heterogeneous materials, and solved some material / structural computational problems. He has published more than 200 papers and reports, 3 books, and completed more than 30 technical reports to government or companies. He has been awarded 9 times of higher prizes.
Now he is engaging in the researches of the multi-scale analysis method and its applications to material sciences and engineering, and big data sciences and applications.
