v6.02.129 SSNL129 — Validation of laws VISC_ISOT_TRAC and VISC_ISOT_LINE on a tensile test

Summary:

This test consists in applying a tensile load to an elementary volume. Three loading speeds are modelled.

The A, B and C models make it possible to validate the law of behavior VISC_ISOT_TRAC (DEFORMATION =” SIMO_MIEHE “) in 3D, D_ PLAN and AXIS. For this, the results obtained are compared with the viscous Rousselier law ROUSS_VISC and DEFORMATION =” PETIT_REAC “degenerate so that the evolution of porosity is negligible. The D, E and F models make it possible to validate the integration of law VISC_ISOT_LINE (DEFORMATION =” SIMO_MIEHE “) in 3D, D_ PLAN and AXIS. For this, the results obtained are compared to those given by law VISC_ISOT_TRAC for the same linear work hardening.
