Abstract
The identification of the material parameters of a given constitutive model can follow diverse methodologies and use distinct sets of experimental data. In order to easily compare different sets of material parameters, it is necessary to know how to establish the equivalence between identification results. This work explores the correlation between sets of parameters of constitutive models concerning the yield criterion and the isotropic and kinematic hardening laws. It is shown that distinct sets of parameters for a given constitutive model (yield criterion and isotropic and kinematic hardening laws) can describe the same material behavior, and a rule for matching the sets is established.
