Abstract: The separate modeling approach of reinforced concrete with LS-DYNA code was applied to numerically simulate the perforation experiments of reinforced concrete by Hanchak, et al, in which the beam elements charactering steel bar were coupled with solid elements characterizing concrete by nodes. The study focused on failure type (FS) of HJC concrete constitutive model, which effects the compression damage of concrete, based on discussions about the damage of concrete influenced by parameters of the hydrostatic pressure and the principal strain. By changing the impact location, the function of steel bar to penetration resistance emerges expressly. The proposed modeling methods and parameters were used to guide experimental study on penetration of reinforced concrete by a penetrator with large mass.
