Resumen:
ABSTRACTA constitutive model based on classical plasticity theory for non-linear analysis of concrete structures using finite elements is presented. The model uses the typical parameters of non-associated plasticity theory for frictional materials and a modifiedMohr-Coulomb yield surface is suggested. Onset and amount of cracking at a point are controlled by the values of the effective plastic strain and thus it can be studied by a posteriori postprocessing of numerical results. The accuracy and objectivity of the model is checked out with sorne examples of application.
