| Abstract: | Hopkinson Bar for high strain rate tests of fiber reinforced composites is developed. It is described that the configuration of the hardware and the development of the system software. The testing method is illustrated with experimental examples. Typical experimental results for carbon fiber under high strain rate are introduced. It means that the system is reliable and effective. |
