미사일 관통해석시 콘크리트 재료모델의 영향

Abstract

In this study, the missile penetration and perforation behaviors were simulated via commercial hydrocode ANSYS LS-DYNA. In simulations, three different concrete constitutive models provided by LS-DYNA were used to estimate the model dependences in perforation simulations. The simulation results were compared with perforation experiment result and the corresponding dependences were discussed.endences in perforation simulations. The simulation results were compared with perforation experiment result and the corresponding dependences were discussed.
