The nonlinear physical behavior of concrete can be represented by models from the theory of plasticity with associated damage. In the commercial software ANSYS and ABAQUS, three distinct models are available that can represent the mechanical behavior of concrete, considering the uniaxial and biaxial states under compression and tension, named the Microplane Model, Menetrey-Willam Model, and Concrete Damaged Plasticity. This article aims to present the theory regarding these models, examples of application, and sensitivity analysis of the plastic and damage parameters in numerically simulated cylindrical specimens. Finally, there is a comparison of the use of these models in a reinforced concrete beam simulated with cyclic loading.
