Simufact material database for Inconel 718 powder

C B
I have few questions about the Simufact material database for Inconel 718 powder, when looking into the flow curves all I could see is the data for the plastic region, I would like to know why the Simufact didn't consider the elastic region. Also in the mechanical properties what is the input for elastic modulus for this material because am not able to find it, did you consider infinite elastic modulus? if yes, could you please explain.
 
Kindly look in to the below plot I got from a simple compression test showing true stress and true strain for IN718 powder at 20C .
In718
Could you please explain why the Simufact database doesn't have any elastic region data.

    Hi,
    the result should look like in the attached video (it is axial symmetric, not expanded, but showing just the "half plane" used for the simulation).
     
    Is your shape (cross section) staying rectangular? If you get a round shape at the OD, there is an issue in the friction, and the theory of the test model does not work. Compare with the model I provided in the forum and per e-mail.
     
    Check the scale used for the result display. It needs to have a reasonable range. There will always be some small numerical spread in the result. Some times the automated scale of the legend takes this as range. You see some thing non-uniform, but all values are between 0.0099999999 and 0.0100000001.
     
    If a time velocity press is defined, the stroke will follow from this definition. The stroke = the moving distance is the integral of the velocity. If the velocity is not linear the only trick is to find the correct end time of the press.
     
    I hope this helps, if not you may want to send your model to support@simufact.de mentioning this chat and my name and I will check what causes the non-uniformity in your results.
