Longhui Zhang BSc DPhil MSc

Postdoctoral Research Associate


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 at the University of Oxford, working on impact resistant design of lightweight materials and structures in Rolls-Royce engine

Longhui’s interest is in experimental impact mechanics, with emphasis on the adiabatic self-heating, constitutive modelling, strain localization and dynamic failure mechanisms of polymers, composite foams and lightweight metals under complex stress states, to provide important findings and results for critical engineering applications as well as being good physics

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