    Abstract
  • Dynamic Brazilian test of plastic-bonded explosives was investigated by split Hopkinson pressure bar (SHPB). The tensile strengths of three PBXs were acquired under different strain rates. The evolution of crack on sample surface was captured using high-speed camera. The strain field was calculated by digital speckle correlation method before samples occurred to crack. The simulation on dynamic Brazilian test was performed using discrete element method, and the simulation model considering meso-structure was acquired.The simulation results show the produce and evolution process of damage and crack, and the simulation results are in accordance with the experimental results.
