    Abstract
  • Symmetrical impact experiments were performed for tantalum, the free surface velocity profiles were measured with VISAR system. Making use of the double wave configurations of shock loading, the shock wave velocities were determined at stresses below 30 GPa, and a very good linear dependent relation of D-up has been obtained. The comparison with the experimental result of high pressure region was also made. Discussion about models for calculating spall strength was conducted. It was found that the spallation strength of tantalum calculated with different models has differences up to more than 30%.
