Qian Weichang, male, Han nationality, born in June, 19 12, from Wuxi, Jiangsu. Academician NLD, doctor, researcher, professor, academician of China Academy of Sciences. He graduated from Tsinghua University in his early years and studied under Professor Wu. He graduated from the University of Toronto in Canada and studied under Professor J.L. Singh. Before the founding of the People's Republic of China, he was a research engineer, Professor Tsinghua University, Professor Peking University and Professor yenching university of the Jet Propulsion Institute of California Institute of Technology. After the founding of People's Republic of China (PRC), he served as Professor Tsinghua University, Deputy Provost, Provost and Vice President, Deputy Director and Researcher of Institute of Mechanics of Chinese Academy of Sciences, Director of Institute of Automation of China Academy of Sciences, Director of Preparatory Office, Academic Secretary of China Academy of Sciences, Deputy Secretary-General of all-china youth federation, Standing Committee of NLD Central Committee, Professor and President of Shanghai Polytechnic University, Director of Shanghai Institute of Applied Mathematics and Mechanics, member of the first discipline evaluation group of the State Council Academic Degrees Committee and member of the State Council Science Planning Committee. Member of the Standing Committee of the National Association for Science and Technology, Minister of Organization, First and Second Vice-Chairmen of China theoretical and applied mechanics Society, Member of the Department of Physics and Mathematics of China Academy of Sciences, Executive President of China Association for the Promotion of Peaceful Reunification, President of China Overseas Exchange Association, etc. He founded the Chinese and English periodical Applied Mathematics and Mechanics, Shanghai Institute of Applied Mathematics and Mechanics, and was one of the main founders of the Institute of Mechanics of Chinese Academy of Sciences.

Qian Weichang is a famous mechanic, applied mathematician, educator and social activist in China. He has written a lot in applied mathematics, physics and China informatics, and made outstanding contributions to the problems of plates and shells, generalized variational principles, perturbation methods, analytic solutions of rings, macro codes of Chinese characters, etc., which are highlighted in the following aspects: 1940 put forward that the nonlinear differential equation in the "intrinsic theory of plates and shells" is called "Qian Weichang equation", and the systematic perturbation method adopted in this theory. 1954' s theory of large deflection of circular thin plate won the second prize of 1956 National Science Award. 1979 won the second prize of 1982 national natural science award for the study of generalized variational principles; 1997 won the Science and Technology Achievement Award of Heliang Lihao Foundation on September 23rd. He is the author of Variational Method and Finite Element, Generalized Variational Principle, Armor-piercing Mechanics and the co-author of Mechanics of Elasticity. In view of his outstanding contribution to the cause of mechanics in China, together with Zhou Peiyuan, Qian Xuesen and Guo Yonghuai, he is recognized as the founder of modern mechanics in China.

In order to strengthen the exchange of achievements in the fields of applied mathematics and mechanics, Qian Weichang founded Appl. Math. Mecha warrior. -English education. And applied mathematics and mechanics of 1980. The contents of the two journals correspond to each other one by one, and the editorial board recommended the system. From its inception to the end of 2002, Mr. Qian has been the editor-in-chief. During this period, he not only personally determined the purpose of running the journal, personally reviewed all the manuscripts, but also personally set up the first editorial board. He is eclectic, promoted backward, and let young people take the lead in practice. At the beginning of the publication, more than 60 editorial boards were mostly young scholars, and most of them were fledgling associate professors or lecturers. Facts have proved that Mr. Qian has a unique vision and knows people well. Of the original 60-odd editorial board members, 8 later became academicians of China Academy of Sciences. In order to expand the influence of the journal, Qian Lao launched the editorial board and organized nearly 50 academic lectures on applied mathematics and mechanics all over the country in the name of the journal, with an audience of more than 20 thousand, which greatly promoted the development of the journal. In addition, Qian Lao also held numerous other international conferences, large and small, which played an indelible role in the development and spread of applied mathematics and mechanics in China.
