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.

    Hello Vignesh,
    sorry for my late reply, I was out of the office for a few days hoping that the community picks up open questions.
     
    What do you mean with "temperature correction model"?
     
    If temperature effects are enabled (this is the default, see Forming Control / Miscellaneous), we convert 90% of the energy needed for plastic deformation into heat. And 90% of the energy needed for friction into heat.
     
    The first can be set as Dissipation Factor in the thermal properties of the workpiece, the later can be set in the Forming Controll in the friction section.
