From August 13th to 15th, at the invitation of the researcher Li Liangbin of the National Synchrotron Radiation Laboratory, Professor Dan O. Haseger of the Department of Chemical Engineering of the Danish University of Science and Technology and Dr. Huang Wei visited the Soft Matter Intelligent Manufacturing Group. On August 14th, Prof. Ole Hassager gave a report entitled “Extensional rheology of polymeric systems” to teachers and students of the research group, and the report was chaired by Prof. Li Liangbin.
In the report, Professor Ole Hassager talked about the basic concept of stretch rheology and introduced the application of FSR extensograph in accurate measurement of tensile rheology. Next, Prof. Ole Hassager combined the research work of their research group and reported on the hot issues in the current stretching rheology. In the end, he also introduced the study of using the finite element method to simulate tensile creep.
After the report was over, students and teachers discussed with Professor Ole Hassager in-depth discussions on the content of the report and their own research.
Ole Hassager was a graduate student at the University of Wisconsin and received a doctorate under the direction of R.B. Bird. His main research interests are in the field of soft material physics, fluid mechanics, numerical simulation and rheology. He has published more than 120 papers in international journals, including high-impact publications such as Nature and PRL. He is the co-author of the "polymer fluid dynamics" textbook, cited more than 10,000 times. Professor Ole Hassager is a member of several national and international scientific committees and councils, including the Danish Independent Research Council and the Rheological Society Executive Committee. He is an associate editor of Fluid Physics (Institute of Physics in USA).
