.. _ConstitutiveModels_theory: Material's constitutive models ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In this section, the different constitutive models implemented in RamSeries are introduced. These models are capable of simulating the rheological performance of different materials, by predicting their nonlinear performance. :ref:`J2 plasticity ` predicts the plastic strains in a material, while :ref:`isotropic damage model ` takes into account the loss of stiffness of a material. .. toctree:: :maxdepth: 1 j2_plasticity.rst damage.rst
