8. Summary of results

This test makes it possible to demonstrate the good consideration of plane stresses for elasto-plastic behaviors VMIS_ISOT_TRAC, VMIS_CINE_LINE, VMIS_CIN1_CHAB, and VMIS_CIN2_CHAB.

The results are identical to the analytical solution. Constraints \(\mathrm{SIZZ}\), which must be zero if the hypothesis of plane constraints is verified, are actually zero when Newton iterations converge with good precision (\(\mathrm{SIZZ}=\mathrm{2.8.E}-5\mathrm{MPa}\) at most, in comparison with \(\mathrm{SIYY}=210\mathrm{MPa}\)), and this for a time CPU and a similar number of iterations.
