Hi All - I am new to FreeCAD and was looking at the material cards. I was wondering if there was a hyperfoam material card I could use which I could input known stress strain data curves? Alternatively is there a way to import actual stress-strain data into FreeCad and how?
Thanks!

Re: FCMAT Stress Strain Data Import
Thanks Bernd for your reply!
I want to model a simple foam block and check the behavior of the foam under compression versus actual stress strain data. I think the best way to do this is would be to import the stress strain data. The link you shared shows potential however I am still struggling still on how to create the FCMat. How would I do this to input the stress strain data? Could you send or share an example file of how to input the stress-strain data into the FCMat?
Many thanks in advance!

Re: FCMAT Stress Strain Data Import
would you like to use FreeCAD FEM for this?
If yes the stress strain curve behind the first sharp bend is not done in the material cards. This is done in the FreeCAD FEM nonlinear material object.

Yes, in nonlinear it only allows for three yield points which unfortunately is not truly representative I believe. Can it offer simply more points to match the stress strain curve?
Re: FCMAT Stress Strain Data Import
This is because I only need these three
how many do you need?
