Under the leadership of Professor Yuan, with the joint efforts of all comrades and the strong support of relevant leaders and departments, the discipline of rheological mechanics has made great achievements. After more than 30 years of discipline construction, the discipline has formed a strong academic team and an academic school with its own research characteristics, which has a certain influence in the world and a certain academic status in China. In particular, his work in the theory of material failure is outstanding, and he has his own research characteristics, creating such branches as "rheological fracture" and "defective rheology". Theoretical research attaches importance to interdisciplinary and multi-scale research. This theory highlights the combination of rheology and damage, rheology-temperature effect-viscosity-dissipation, and emphasizes the combination of macro-fine/nano-micro. Before 200 1, it was supported by five national natural science foundations and 1 China-US Joint Natural Science Foundation. Establishing the failure theory of rheological materials combining macro and micro is a world-leading work from theory to practice, with high academic value and wide application range, which has been recognized by colleagues at home and abroad. The key project of the National Natural Science Foundation "Material Failure Theory of Rheological Objects with Defects" passed the project acceptance organized by the National Natural Science Foundation on 200 1. The expert group believes that the achievements made by the research group are innovative and international frontier in the study of material failure mechanics of rheological objects with defects, which not only has important basic theoretical significance, but also has broad application prospects. The research results have reached the international advanced level and the comprehensive evaluation is excellent. Since 200 1, this direction has made research progress in two fields: multi-scale theory and macro-fine-micro model. Rheological materials-polymers have been supported by eight national natural science foundation projects, which shows that academic circles recognize and support the research work and achievements in this direction.
Professor Yuan is one of the main founders of China Rheology Society, and participated in the formulation of 65438-0978 national rheological development plan. 65438-0984, the national symposium on rheology was held in Qingdao, with Hunan University as the keynote teacher. More than 70 people from universities and research institutes all over the country participated in it, which played a positive role in promoting the development of rheology in China. From 65438 to 0985, Professor Yuan was one of the chairmen of the conference and held the "First National Academic Conference on Rheology" in Changsha. 65438-0987, Professor Yuan was one of the chairmen of the conference and held the second national academic conference on rheology in Chengdu. Up to now, the national academic conference on rheology has been held for eleven times.
