Elastic modulus vs SS curve

Hi.

Say that I use a non-linear material model, like plasticity von mises, and then define a SS curve.

Normally I would start my SS curve at or directly above the yield strength of the material.

Below this point the elastic modulus handle the response

 

What happens if I add data for stress and strain below the yield strength in my SS curve?

Will the solver still use this data instead of the elastic modulus, or will it ignore this information and use E modulus until yield?

 

I can't try it because I don't have premium/non-linear, but I'm curious how this works.

Thank you in advance for your response.
