  • Because there are great systematic deviations in viscosity coefficients at high pressure when measured by different experiment techniques, it is necessary to improve the experiment technique and obtain more reliable experiment data. In this paper, by the method of improvement on flyer-impact technique, the oscillatory damping and reverse-phase oscillation process on sinusoidally small-perturbed shock front of aluminum at 101 GPa is detected. The shear viscosity coefficient is deduced to be about 800 Pas based on Miller and Ahrens' analytic solution for non ideal initial condition.
