There are several constitutive models, most of them based on the Theory of Plasticity and the Continuous Damage Mechanics. ABAQUS software has a concrete damaging plasticity model known as the Concrete Damaged Plasticity Model (CDP). The objective of this paper is to study the CDP with the purpose of elucidating its use and adoption of parameters, besides modeling a beam in reinforced concrete and comparing the results obtained with experimental results. First, a review about the model is carried out based on its theoretical formulation from previous studies. After that, three-dimensional beams are modeled in 4-point bending tests. There are adopted parameters of different authors as inputs to compare. No satisfactory results are found for the beams. It is suggested, for future papers, the adoption of different parameters that are adequate to the experimental results.
