1982 Wang Qingyuan, 17 years old, was admitted to Chengdu University of Technology (now Sichuan University) from a remote county in Chongqing. Since then, he has forged an indissoluble bond with high-performance structural materials and engineering mechanics. From bachelor's degree to master's degree in China, to doctor's degree in Paris Central University, a famous French university, and then to post-doctoral degree in Paris Institute of Technology and Purdue University Institute of Technology, he has conducted academic exchanges in Japan, France, the United States, Canada, Germany, the Netherlands, Belgium, Spain, Italy, Austria, Sweden, South Korea and other countries 10. In June 2000, he was still in Japan. In less than a year, he officially returned to his alma mater, Sichuan University, as an imported talent, and was quickly promoted to professor and doctoral supervisor. Along the way, he studied tirelessly; Along the way, he constantly pursued Excellence; Along the way, he worked hard to innovate and used his son's sincere heart to strive for excellent studies and achievements to repay the motherland.

Patriotism is sincere and eternal.

Wang Qingyuan, who has excellent academic performance, stayed in Chengdu University of Technology to teach. 199 1. In order to spread her wings in the professional field, Wang Qingyuan went to Paris to study on 1995, and studied for a doctorate at the Central University of Paris.

Before he left, in a letter to his tutor and college leaders, he repeatedly said: Going abroad for further study is not to gild the individual, but to lay a solid professional foundation, improve his professional quality, and make a greater leap in his professional ability and scientific research ability.

Many people in the world have a saying about international students: studying abroad is for the improvement of personal future and family living standards, that is, fame and fortune. Facing the reporter's hesitation, Professor Wang Qingyuan said frankly: "Going abroad for further study is really beneficial to a person's future development. But at the same time, I thought about a son's responsibility to his mother. A famous saying by Zheng Banqiao, an ancient man, "One good deed deserves another, and it is time to study" deeply inspired me. The younger generation grew up happily in the embrace of the motherland. It is true that one's studies and career cannot be separated from one's efforts, but without the education of the state and schools and the excellent competitive environment provided by this era, we cannot succeed. Therefore, our success is due to our motherland. We can't just accept goodwill and be indifferent. On the contrary, we should consciously bring the responsibility of loving the motherland and rejuvenating China into our study and career, build and serve the motherland and travel around the world. "

Recalling his stay in Paris, Wang Qingyuan will never forget a great man, whose strength of personality deeply influenced and encouraged him, making his love for his motherland grow day by day rather than weaken. That is * * * and the first prime minister of Zhou Enlai.

Paris is the place where Premier Zhou Enlai stayed in Europe for work-study programs when he was young. There, young Zhou Enlai became one of the earliest party member of China's * * * production party, and embarked on the glorious road of professional revolutionaries. Premier Zhou's lofty spirit and great personality are immortal models. To love and respect Premier Zhou, first of all, we should learn from his sincere heart of loving the motherland and his noble character of being honest, strict with self-discipline, seeking only dedication and not expecting anything in return. His image as a great public servant who is willing to bow his head for the people will always inspire him. On the occasion of the 0/00th anniversary of Premier Zhou's birthday, the leaders of the All-France Federation and the Paris Federation of Students planned and organized the activities to commemorate the 0/00th anniversary of the birth of Premier Zhou. They came to the former site of Godfrey Street 13 in Paris, where Premier Zhou once lived during his visit to France, to lay flowers in memory of the great man. Wang Qingyuan and his classmates said that as a new generation of cross-century overseas students in China, they should remember Premier Zhou's great life and brilliant achievements, learn, inherit and carry forward the spirit of Zhou Enlai-study hard for the rise of the Chinese nation and contribute their intelligence and wisdom to the modernization of the motherland.

It's hard and fun to practice internal skills.

Wang Qingyuan made full use of every moment of studying abroad and the best scientific research conditions there to study ultra-high cycle fatigue, and engaged in theoretical and experimental research on ultra-high cycle fatigue fracture of high-performance alloy materials used in aviation, automobile and other fields. In order to successfully design an ultra-long life ultrasonic fatigue experimental system and calculate complex calculation formulas, he can work continuously in the laboratory for more than 10 days. When he is hungry, he matches a French bread with tap water. In the days when he was studying abroad, his schedule was mainly based on study and experimental work. Work and study strictly, and live as simply as possible. Wang Qingyuan said, "It's now or never. I want the speed and efficiency of time. As for football, track and field, swimming, traveling and other hobbies, I am only in the mood to do it after working for a period of time. It is even more important to play football with my son and enjoy the beautiful scenery of nature with my wife and children. His wife said that he; It's like an ascetic monk who never complains when he comes home, but often acts like a victorious soldier. "

Doing business, inheriting and innovating

Professor Wang Qingyuan said that fatigue is one of the main forms of damage to materials and structures. Fatigue, damage, performance degradation, failure and destruction of large engineering structures and military and civil aircraft under long-term (even exceeding the original design life) load (even overload) and corrosive environment are increasing, which seriously affects and endangers public safety. Durability, safety and maintainability should be considered in engineering structures; Small mechanical and micro-nano MEMS as small as 1- 10 mm also need to consider the long-term reliability and stability under electrical and mechanical loads; The bones and tissues related to ourselves will also suffer fatigue damage and fracture due to various repeated loads such as stretching, compression and shearing in daily activities or sports. Yvonne Wang Distance Education 1999' s doctoral thesis published in International Fatigue Fracture is such a research. A variety of metal materials were tested by a 20KHz piezoelectric ultrasonic accelerated fatigue testing machine. Experiments show that ultra-high cycle fatigue cracks often originate in the sample. After the stress cycle of more than 107 cycle, the failure of the sample continues. It can be seen that many high-strength steels have no so-called fatigue limit (infinite horizontal asymptote appears after 106 ~ 107 weeks), only fatigue strength or durability limit. Wang Qingyuan believes that it is dangerous to use only the data in the week of 107 as the basis of fatigue design. In his research, he also found that the ultra-high cycle fatigue S-N curve of materials can show two other limit types, namely, continuous decline type and step decline type, which are different from the traditional specifications. A large number of fatigue tests also prove that in high cycle fatigue (>: 107 cycle), the crack originated from the specimen, on the contrary, in low cycle, the fatigue crack originated from the surface. This paper has aroused widespread concern in the field of international fatigue, and has been cited by foreign counterparts for more than 20 times in recent three years.

For research work, Wang Qingyuan is not limited to learning and inheriting. He said that only creative research can produce innovative results; It is the need of the times and social development to produce innovative results. We young scientific and technological workers should cultivate creative personality and creative thinking and lay a solid foundation and conditions for innovative achievements.

During his study abroad and postdoctoral research in France, Wang Qingyuan undertook millions of dollars in scientific research projects and made significant progress. Among them, there are two most innovative ones. First of all, he successfully designed and implemented five sets of ultra-long-life ultrasonic fatigue experimental systems in the research of high-cycle fatigue of parts in many industrial departments. For the first time, the ultra-long life (65.438+billion cycles) fatigue experiments of ultra-thin plates, tubular materials, filamentary materials and high temperature and high pressure hydrogen environment were successfully realized. Secondly, Wang Qingyuan used his own system to conduct a lot of experimental research and analysis on the fatigue fracture of many kinds of high-performance alloy materials with strength ranging from 300MPa to 2500Mpa, such as 10 for automobiles, high-speed trains and aerospace, and put forward the mechanism that ultra-high cycle fatigue cracks often originate in the sample and the characteristic that the fatigue stress-life curve decreases step by step after 107 cycles, which broke through the existing fatigue limit.

Show great ambition and goals.

After returning to work in Sichuan University in July, 2006, Wang Qingyuan began to implement his ambitious plan, actively applied for scientific research funds, and strived to establish and form distinctive research groups and laboratories as soon as possible. In order to create conditions for scientific research, Wang Qingyuan accepted an invitation to visit Japan again as a fund project researcher of Japan Academic Promotion Association, and used Japanese funds and conditions to continue his research work. He used Japanese research funds to publish more than 0 research papers 10 signed by Sichuan university, and reported papers at international conferences or served as chairman of conference chapters for 5 times. During this period, in order to strengthen the international exchanges and cooperation of Sichuan University, he invited famous scholars to Sichuan University for academic exchanges many times, flew back to the motherland for six times, or gave lectures to graduate students and undergraduates, or directed graduate students' scientific research work and papers, or carried out academic exchanges and cooperative scientific research work.

Wang Qingyuan's diligence and outstanding contributions have also won him high honors. Wang Qingyuan said that although honor is gratifying, it is more of a heavy responsibility.

For this important task, Wang Qingyuan traveled across oceans to study abroad. For this heavy responsibility, he remembered Premier Zhu Rongji's ardent expectations for international students including him when he met with them during his visit to France 1998: "We are waiting for you!" . Wang Qingyuan said with emotion: "We should realize our own life value in the construction and dedication for the motherland. Strength comes from hard work, you are doing practical things, but you are worthy of raising my motherland and people. "
