5. Summary of results

The following curves represent the various comparisons between Code_Aster and Lawyer (behavior law calculation program, not finite elements), in terms of isotropic pressure (Figure), plastic volume deformation (Figure) and monotonic and cyclic isotropic work hardening coefficients (Figures and).

The differences observed between the two models for the values of the cyclical mobilization factors are due to the different management of the kinematic variables over time. Their values are only different when cyclical mechanisms are not active.
