Wang Qingyuan

Mr. Wang Qingyuan has been engaged in research on materials and structural mechanics for a long time, and has achieved a string of significant systematic innovative results. Notably, he pioneered a high-frequency vibration accelerated fatigue testing method and developed the world's first comprehensive experimental system for accelerated ultra-long life vibration testing. This system allows ultra-long life accelerated testing under various conditions such as low temperature, high temperature, vacuum, and corrosion, and under multiple stresses, including tension and compression, tension-tension, torsion, bending, and slight vibration. International peers highly praised Mr. Wang's achievements, hailing his work as groundbreaking by stating, "Wang et al. provided the first experimental evidence." His research reveals that the stress-life (S-N) curve declines again after 10⁷ cycles. This breakthrough overcomes the limitations of defining existing fatigue limits and enables experimental research and accurate descriptions of fatigue behavior with an ultra-long life of over one billion cycles. Additionally, it offers a new experimental approach for long-life high-reliability design. Mr. Wang proposed a new mechanism of ultra-long life fatigue crack initiation, which was acknowledged by international peers as "The findings of Wang et al.". He is the pioneer in establishing a ultra-long fatigue life prediction model based on crack initiation, which was recognized as "Wang et al. …the first to discuss critically...". Mr. Wang also developed a theory and technique for assessing fatigue life and reliability under small sample conditions, which have been "successfully applied in estimating notched fatigue lifetime" according to industry peers. This breakthrough resolves the challenge of insufficient data for large components and provides essential theoretical and technical means for the high-performance and long-life design, as well as safety and reliability assessment of major equipment. These research results have been successfully applied in the long-life anti-fatigue design and safety assessment of major equipment in China, such as engines, turbines, and large composite box girder structures.

Mr. Wang has published over 100 theses in top journals, including International Journal of Fatigue (IJ Fatigue), Journal of the Mechanics and Physics of Solids (JMPS), International Journal of Mechanical Engineering, Advanced Science, Advanced Materials, Nature Communications, and Nature. Notably, he has published 43 theses in IJ Fatigue, and six of his theses on fatigue have been cited in four regular issues of Science and Nature over the past three years. He has been consistently elected as one of the "Highly Cited Chinese Researchers" released by Elsevier for nine consecutive years and included in the World's Top 2% Scientists list by Stanford University for single year and career-long impacts. He has been granted over 50 invention patents and published five academic monographs. Mr. Wang received the National Second Prize for Natural Science, the First Prize for Natural Science from the Ministry of Education, two First Prizes for Scientific and Technological Progress in Sichuan Province, and the First Prize for Scientific and Technological Progress from the Chinese Society of Theoretical and Applied Mechanics (CSTAM) as the first author. He has been a member of the Discipline Review Group of the Academic Degrees Committee of the State Council and served as the Secretary-General of the Teaching Guiding Committee of Mechanics Major for Higher Education Institutions under the Ministry of Education. Additionally, he has held positions as Executive Director of the CSTAM and Deputy Director of the Experimental Mechanics Working Party under the CSTAM. He has also acted as Associate Editor or Editorial Board Member of academic journals such as Fatigue & Fracture of Engineering Materials & Structures (FFEMS) and IJ Fatigue. Furthermore, he has chaired numerous international and domestic conferences, including the 6th International Conference on Very High Cycle Fatigue, Chinese Congress on Mechanics 2021+1, etc. His outstanding achievements in and contributions to the long life and high reliability fields have led and promoted the development of related research. He has been selected as a winner of the National Science Fund for Distinguished Young Scholars, a candidate for selection as a new academician of the Chinese Academy of Engineering, and a Fellow of the International Association of Advanced Materials (IAAM).
