Research project - Investigation of the dynamic response of concrete at high strain rate using Hopkinson Bar spalling test
Supervisor: Dr Luming Shen
Concrete is widely used in structures such as apartments, bridges, nuclear power stations and tunnels. These structures can be subjected to considerable dynamic loadings such as earthquakes, industrial accidents (i.e. explosion) and projectile impact (i.e. terrorist attacks). Hence, the understanding of the dynamic response of concrete under high strain rate is significant.
Hopkinson Pressure bar is an apparatus that is used to test the dynamic behaviour of a material. It is capable of producing strain rates up to 104/s (the strain rate of a quasi-static test is about 10-6/s).
The aim of the project is to investigate the dynamic response of concrete at high strain rate using the technique of spalling test. Meanwhile, it is hoped to improve the accuracy of Hopkinson bar spalling test by introducing a new technique to capture the starting point and the wave velocity as well as to optimize the striker shape. Finally, based on the experimental data, it is also hoped to develop a new material model for predicting the dynamic response of concrete
