According to the characteristic of remain tungsten alloy penetrators in recover crater that was destroyed in penetrating end, spread peculiarity of plastic wave of tungsten alloy in impact has been studied using two stage light gas gun. Results show that in impacting plastic wave speed and elasticity wave speed in tungsten alloy are same measurement,4.208 km/s and 3.067km/s respectively, plastic wave speed was slightly slower than elasticity wave. Penetrating isn't actually one dimension strain issue and penetrating process temperature was higher than experiment in light gas gun, so plastic wave speed was actually lower. But according to the penetrating time obtained by calculating, and analyzing destruction of penetrators in penetrating process end, one can say that plastic wave speed should has same measurement with calculation. All these results are difference with the assumption made for analysis that plastic wave speed was actually much lower than elasticity wave speed in penetrating process. Destruction of penetrators tail in a plastic wave spread process can be pulled down by elasticity wave backward spread, this can take energy out from penetrator and bring effect on penetration depth.
