Numerical simulation for penetration of long rod to steel target

The penetration process of long tungsten alloy rod to steel target and the target damage were numerically studied with Lagrange method and Johnson-Cook constitutive model coupled with ANSYS/LS-DYNA3D. The simulations reveal that the long rod penetration consists of four various phases, and in a certain velocity range, Lagrange method and Johnson-Cook constitutive model are suitable for the simulation of long-rod penetration. Regarding Alekseevskii-Tate model, the assumption of consistent penetration velocity may be further conducted.
