In the material properties tab of hyperlife, there is the possibility to select 3 surface treatments (Nitrided, shotpeened, coldworked) Nitrided applies a correction factor of 2 while shotpeening and coldworks don't apply any correction factor.

My question is: Why there is the option of apply shotppening or coldwork when the result won't change in any way?
