Dao-Ying XI; Yong-Lai ZHENG and Tao ZHANG (Department of Earth and Space Sciences, University of Science and Technology of China, Hefei 230000, China)  
This article has processed the experimental study of stress wave propagation using Hopkinson Pressure Bar, andmeasured with groups of PVDF stress sensors, obtained the waveform characteristics and the attenuation constant, and got the dynamic constitutive relations using Lagrangian analysis method.
