A reliable choose of material models is quite important to correctly conduct the numerical simulation of copper jet into water. In the present paper, we compared three copper models, i.e., Steinberg Guinan, Piecewise JC and Zerilli Armstrong models and two water EOS of Mie-Grüneisen and Polynomial. With referencing the experimental results, the numerical simulations of copper jet into water were carried out and analysed by employing different material models in Euler algorithm of AUTODYN. It concluded that Zerilli Armstrong model was suitable for copper and Shock EOS was suitable for water.
