Dr

Longhui Zhang BSc DPhil

Researcher and Engineer in UTC

Biography

Dr. Longhui Zhang holds a PhD in Mechanical Engineering (2018) from Technion-Israel Institute of Technology and graduated in Solid Mechanics (Direct BSc-MSc) from South China University of Technology. He is currently a researcher and engineer working in Rolls-Royce University Technology Centre (UTC) at the University of Oxford.

Inspired by working and completing a series of UTC industrial projects, Longhui's interest is in solid mechanics of advanced engineering materials and structures under impact loading, with emphasis on dynamic deformation and failure under complex environments and stress states, to provide important findings and results for critical engineering applications as well as being good physics

 Longhui is a member of DYMAT society and International Society of Impact Engineering, Chinese Society of Theoretical and Applied Mechanics, and serves as a monthly peer reviewer for Mechanics of Materials, Materials Science and Engineering: A, International Journal of Impact Engineering, Journal of Dynamic Behavior of Materials al. about 20 journals.
