The IRIS 2012 benchmark  was devoted to compare various modelling of impact on reinforced concrete slabs. Its aim was to improve the methods used and to provide guidance to assess the integrity of structures impacted by missiles. During this benchmark, it appeared that damage plastic models developed in commercial software worked reasonably well to predict structural damage. This is the reason why a 3D constitutive model of this type, named DPDC (Damage Plastic Dynamic Concrete), was elaborated and introduced in EUROPLEXUS, a general finite element code for fast transient analysis of structures jointly developed by the CEA and the European Commission (EC –JRC ISPRA) and other partners of whom EDF. The model developed for industrial purposes should have been robust, efficient and easy to use. It was freely inspired by whose model presents asound theoretical basis and a reliable calibration procedure. After a short theoretical overview of the model, numerical implementation and calibration procedure are succinctly described, and then comparisons with tests are presented.
