True stress vs effective strain curves in ls-dyna

Hi @Friendly

Since this related LsDyna solver input, I would suggest you get in touch with Dyna support. 

I think it works. the yield point is the beginning of plastic process. the load curve should start with a plastic strain=0 and a plastic stress=yield stress. Of course you should make a transfer to the effective stress and effective plastic strain.

Hi thanks for your answer! Do you know whether it is better to put in effective stress vs. effective plastic strain up to the ultimate stress Point or to extrapolate the remaining curve with a voce-equation? The Problem with the voce-equation is, that my material becomes very ductile for some reason.
