Non linear material curve

Giuseppe Conte

Hello to everyone,
which material curve should I use for a nonlinear analysis?
Engineering or true curve?
Do I have to use any tricks?

thanks in advance

just remember that the stress x strain curve is input in Pascal.

 

I found that you can also define it as true stress curve, by adjusting the header of the csv file, in case you import it.
