9. Summary of results

With less than \(\text{1\%}\) difference between model ROUSS_VISC (degenerate) and model VISC_ISOT_TRAC regardless of the loading speed applied, we can assume that the addition of the viscous component in the model VISC_ISOT_TRAC is correct.

On the other hand, the very small differences (less than \(\text{0.02\%}\)) observed between the solutions obtained with VISC_ISOT_LINE and VISC_ISOT_TRAC for linear work hardening also make it possible to validate the implementation of the model VISC_ISOT_LINE.

In all cases, less than 10 local iterations are required to reach convergence (precision \({10}^{\mathrm{-}9}\)).
