This proceeding presents the finite element (FEM) modeling of a soft missile impact benchmark case called Meppen II/4. The benchmark was launched by OECD/NEA IAGE in 2010. The target in the test case II/4 was 6.5 m x 6.0 m x 0.7 m reinforced concrete slab. The missile was ca. 6 m long steel pipe with the mass of 1016 kg. The impact speed was 248 m/s. The FEM analysis was carried out using Abaqus/Explicit-6.10 software. A so called microplane material model, to model concrete, was adopted from the literature and it was implemented as a user subroutine to the Abaqus/Explicit. The missile load was modeled in this study by using well-known Riera method. The concrete slab reaction force and displacement results achieved in this study were satisfactory. The FEM model predicted cone formation and the radial cracking of the concrete slab.
