Presently, the characterization of metal materials is becoming increasingly important due to the development of new materials, which is often performed numerically. Therefore, the accuracy of software simulation totally depends on the quality of the constitutive models and of their parameters. Hence, in this work, it is performed a loading path which allows to attain the most unique and distinguishable information for the parameter identification. This methodology is presented for two kinds of material.
