Numerical Simulations on the Perforation of Metal Plates under Normal Impact by Conical-nosed Projectiles
This paper examines the perforation of Weldox460E steel plates struck normally by rigid conical-nosed projectiles through numerical simulations. The modified Johnson-Cook constitutive relation and the Gruneisen equation of state for metal plates are implemented in ABAQUS/Explicit as a user-defined material model by means of a subroutine (VUMAT). Numerical simulations are conducted on the perforation of Weldox460E steel plates struck normally by conical-nosed projectiles and flat-ended projectiles, it is shown that the numerical results are in good agreement with experiments. Finally, the effects of various cone angles of conical-nosed projectiles on the failure modes of metal plates and the energies absorbed for perforation are discussed.
