Biography

Dr Yuan Xu obtained her PhD degree in civil engineering from Sichuan University in 2018, specialising in rock dynamics. Since then, she has been working here as a postdoctoral research associate in the Impact Engineering Laboratory.

She is currently engaged in the development of a high-speed loading system for characterising dynamic behaviours of advanced aerospace materials under extreme environmental conditions.

Research Interests

  • Development of a novel Hopkinson bar system
  • Rate dependent material characterisation
  • Advanced loading for pressure and rate-dependent behaviours characterisation
  • Numerical simulation of rate-dependent behaviours
  • Development of new methods for fracture toughness testing

Current Projects

  • CornerStone project at Oxford UTC, Rolls Royce, EPSRC, 2018-2022  This project focuses on the development of a novel Tension Torsion Split Hopkinson Bar apparatus conceived to achieve an arbitrary combination of tension and shear at high strain rates in a single loading event.
