In this paper an elastoplastic constitutive model based on a modified Mohr-Coulomb yield surface for non linear analysis of concrete under tension and compression states is presented.Cracking is controlled by the amount of effective plastic strain and it can be studied by a posteriori postprocessing of numerical results. The accuracy and objectivity of the model is checked out wíth one example of application
