Hi all,

I have few doubts about in defining SS curve. I have taken the tension test of AISI 301 steel. Which is 3/4 Hard. I got the following True stress strain curve.

But when i take the account of the Ramberg Osgood curve fitting then curve shifted to bit above.Which is below

Or i have to choose the another curve fitting.

Can anyone explain how it affect simulation. Because if i choose normal SS curve without curve fitting then i get the warning  regarding ETan.
