8. F modeling#
8.1. Characteristics of modeling#
This modeling is identical to modeling A. The only difference is in the management of the time step. The time discretization chosen is minimal: \(\mathrm{0,1 };\mathrm{0,9 };\mathrm{1 };\mathrm{2 };3\).
The time step is re-cut if, at convergence, the maximum cumulative plastic deformation increment exceeds \(\mathrm{0,1}\text{\%}\).

In addition, in a second series of calculations, we test the error indicator due to the non-radiality of the load: using a rough temporal discretization, as before, we activate the subdivision of the time step if the error due to the non-radiality exceeds 2% (RESI_RADI_RELA =0.02). This test is carried out for 2 equivalent behaviors: VMIS_CINE_LINE, VMIS_ECMI_LINE.. The results are identical for both behaviors:
