9. Summary of results#

The following curves represent the various comparisons between Code_Aster and Xloi (program for calculating the law of behavior, not finite elements, on a hardware point). The Hujeux law implemented there is identical to that found in GEFDYN), in terms of deviatory stress (Figure), total volume deformation (Figure) and deviatory (Figure) and isotropic (Figure) and isotropic (Figure) work hardening coefficients.
