Kai Liu DPhil

Dr. Kai Liu is a post-doctoral research associate in Impact Engineering Laboratory (IEL), University of Oxford. He is undertaking the project ‘Pressure and Strain rate Dependent Behaviour of Composite Materials for High-performance Aerospace Applications’. He received his PhD in Civil Engineering from Monash University in 2020, and prior to joining Oxford, he was a researcher fellow in impact engineering at Monash, working on the dynamic fracturing behaviour of geomaterials under multi-axial loadings and Triaxial Hopkinson Bar Techniques.

● Triaxial Hopkinson Bar Techniques
● High-speed Three-dimensional Digital Image Correlation (3D-DIC)
● Confinement and Rate Dependent Behaviours of Solid Materials
● Dynamic Fracturing Behaviours of Geomaterials under Multi-axial Loadings
● Micro-structural Characterization and Failure Micro-mechanisms
