Professional experience

Dr. Xin received a B.S. degree in engineering mechanics from the University of Science and Technology of China in 1985. After a period of graduate study in Qinghua University, China, he was awarded a Sino-British Friendship Scholarship from the British Council and admitted to the University of Sheffield for Ph.D. study in 1988. He obtained a Ph.D. in mechanical engineering from the University of Sheffield in 1992. He then worked as a post-doctoral researcher in the University of Cambridge from 1993 to 1995, and in the Ohio State University from 1995 to 1998. He joined the Mechanical and Nuclear Engineering Department at Kansas University as an assistant professor in 1998 and as an associate professor in 2003.


Xin’s research is focused on computational mechanics, micromechanics, and materials. Early in his career, he developed a micromechanics-based fatigue growth model which enabled the prediction of fatigue crack growth in materials with grain microstructures, and validated it with experiments in Al-Li alloys. His work in dislocation mechanics solved several open problems in the dislocation field including dislocation loop generation from inhomogeneities, dislocation movement across grain boundaries, and microcrack formation, coalescence, and growth. He developed a general Finite Segment Method for the investigation of bulging and sweeping of dislocations under arbitrary force field. His research of cyclic powder compaction of metal matrix composites provided insight into the hyperplastic deformation of heterogeneous metal powders under cyclic loading. More recently, Dr. Xin’s research targeted computational mechanics including Finite Element Method, Meshless Method, and Peridynamics with applications in fracture and composite materials.

Academic highlights

Xin authored and/or co-authored one undergraduate textbook, over 30 journal papers, and over 35 conference papers. He has supervised four Ph.D. students, 14 Master’s students and three post-doctoral researchers. He has also served as conference session chairs, proposal reviewers for national and international funding agencies, and paper reviewers for over 20 scholarly journals.
