Fig.11 Numerical simulation and experiment result comparison The mechanical properties of the 316L austenitic stainless steel material obtained under different cold working amounts are shown in Table 3.

Table 3. 316L ASS material mechanical properties with different cold deformation. Cold deformation σ 0 /MPa δ 10% 426 0.0067 20% 520 0.0053 30% 552 0.0051 40% 587 0.0044

It can be seen from Table 3 that as the amount of cold processing increases, the yield limit σ 0 of the material increases continuously, and the reduction factor δ decreases.
