Hello again,
Could someone confirm whether (log) true stress -strain values are the right inputs for the Von Mises curve option?. This is the way to go in other solvers but just wanted to be sure as I have not found this detail in the documentation.
Thank you in advance,
Roger
I was wondering the same thing. Should I use Engineering or True Stress-Strain data?
Thanks,
Mike
Hi zhuangs,
I hope that this information is added to the online-help.

I selected a "Steel (AISI 1050) Annealed" in von Mises curve model (Fig.1). Same material properties of Matweb is shown in Fig.2.
I think that a nominal stress is used to express a tensile strength (Ultimate) in Matweb.
In Fig.1, Index 7 of Mechanical SS data table, Strain is 0.237 (mm/mm) and Stress is 636.386 MPa. On the other hand, Elongation at Break is 24%(=0.24), Tensile Strength (Ultimate) is 635 MPa in Fig.2.
Nominal stress and strain are used to SS data table? I have some misunderstanding?
