Numerical simulations of missile impacts on reinforced concrete plates: IRIS-2010/2012 benchmark project

Numerical impact simulations were performed using an explicit dynamic code, LS-DYNA, and the initial FE model was updated through numerous parametric studies. Considering the symmetry of the structure, an updated model was constructed for ¼ of the structure, and the stiffness and mass of the supporting structure was considered. Loading function with a fictitious loading plate was applied instead of modeling projectiles to reduce the computation time. Three concrete models, Concrete damage rel. 3 (*MAT_072R3), Winfrith concrete (*MAT_084-085), and CSCM concrete (*MAT_159), were used for the impact simulations and the results were compared.
