4. B modeling#

4.1. Characteristics of modeling#

Pre-work hardening under tension then cycles with imposed deformation, comparison VISCOCHAB and VISC_CIN2_MEMO. 250 steps of time for 10 cycles.

4.3. notes#

The difference of \(\text{0.8\%}\) on the constraints at the final moment fades away if we refine the time step: with a time step twice as fine, the difference becomes \(\text{0.4\%}\).
