Introduction: Cui Junzhi (1938. 7. 12.--), a native of Xinxiang City, Henan Province, is an expert in computational mathematics, computational mechanics and software engineering. He was graduated from Northwestern Polytechnical University in 1962. Now he is a researcher in the Academy of Mathematics and Systems Science Chinese Academy of Science. In his early time, he was committed to the finite element method research. In 1964, the first general finite element program for plane problems in China was developed, which solved the complex stress analysis problem of the Liujiaxia dam. In 1973, he revealed the relationship between the stress state in the contact body and the loading path, which effectively solved the difficult problem of stress analysis of complex structures in Gongzui Dam with joints in operation and reinforcement in operation. Since 1980s, he has been in charge of and participated in the development of "General Finite Element Program System", National Program--"Building Engineering Design Software Package" and National Nature Science Foundations of China--"Finite Element Method Software Environment". At the same time, aiming at the methodology of scientific and engineering application software development, he proposed an algorithm adaptive organization method and system construction mode. In the past twenty years, a high-order multi-scale analysis method, which combines macro-structure with micro-structure and integrates material and structure analysis, has been developed to predict the properties of composites and analyze their structures. He won the second prize of National Award for Natural Sciences in 1981 and many other awards (more than 7 times for second prize in the level of province-ministry-academy). He Independently and cooperately (main contributor) published more than 150 papers and 3 monographs. In 1995, he was elected as an academician of the Chinese Academy of Engineering.
