Simufact material database for Inconel 718 powder

C B over 1 year ago

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 .

Could you please explain why the Simufact database doesn't have any elastic region data.

Hello Christian,

I would like you to take a look in to the model which I have sent you before and please confirm why am I getting high temperatures in the workpiece when I replace my dies with Rigid with heat conduction instead of with out heat conduction. since I replace my dies with heat conduction the temp in the workpiece should be less compared to the model with dies without heat conduction right. May I know if there is any mistake in the model with respect to heat transfer parameters.

Thanks,

Vignesh.
