At the invitation of College of Materials Science and Technology, Zhai Tongguang, Associate Professor, University of Kentucky,USA gave a lecture titled "Microstructure-based models for simulation of short fatigue crack initiation and growth in 3-D" on December 28th. Xu Xueyu, the Party Committee Secretary, Zhan Hongbing, Dean of CMSE along with dozens of teachers and students were present at the lecture.
First of all, Professor Zhai gave a brief introduction to his research team and their work on the aluminum alloy fatigue behavior and crack mechanism research results. Then, he demonstrated the quantitative research methods of alloy texture and properties, the quantitative behavior of short fatigue crack and the method of life prediction of alloy. The research team found that texture and short fatigue cracks and alloy life has an important correlation, and to this innovation crack, crack test, the first quantitative analysis of the grain size of the impact of short fatigue cracks. An simple approach as it is, it promises a high practical value in engineering applications. Finally, an in-depth discussion was carried out among Professor Zhai and teachers as well as students of CMSE.
After a visit to the laboratories in CMSE following the lecture, Prof. Zhai offered some valuable advice about academic researches in CMSE.
