%X This article describes a method which combines the static pressure experiment,dynamic experiment and theoretical calculation to obtain the parameters in the SCG constitutive model for tungsten alloy under high pressures. By using the constitutive model we obtained in numerical simulation that the calculated profiles of particle velocity are in accordance with the experimental results. We also conducted some other simulations by using different constitutive models and compared them with experimental results. The results show that the constitutive model we obtained was the best.
