Though CDP adopts a crack Concrete plasticity model in ABAQUS incorporates the effect of moderate confining pressure and irreversible plastic damage. Concrete and rebar in the models are considered as solid and rod elements, respectively. Riedel (2000) shows an overview about existing modelling approaches, where the Concrete Damaged Plasticity model based on Lubliner (1989) is chosen. Stress-based plasticity models are useful for the modelling of concrete subjected to triaxial stress states, since the yield surface corresponds at a certain stage of hardening to the strength envelope of concrete (Leon, nonlinear FE models. Inelastic behavior of concrete, mainly influenced Jankowiak T, Lodygowski T.
