2.1.3. 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. J2 plasticity predicts the plastic strains in a material, while isotropic damage model takes into account the loss of stiffness of a material.
