Plastic Strain Data for Steel and PTFE

[bogiedreamer]

Is there a material data library in Abaqus? I need plastic strain data for Steel and PTFE.

I found this steel data from an Abaqus tutorial from a University, could anyone verify that it is correct?

*ELASTIC
210.E09, 0.31

*PLASTIC
200.2E06, 0.0
246.0E06, 0.0235
294.0E06, 0.0474
374.0E06, 0.0935
437.0E06, 0.1377
480.0E06, 0.18

If your units are Pascals, then it is probably correct. You should be careful about blinding using material data...

I agree with vumat721 - you need to be careful about defining your material, as it is as important as the mesh and boundary conditions in correctly defining a model.

Also, what sort of steel are you trying to model? The yield stress of steel can vary widely from low carbon (~400 MPa) right up to the highly alloyed steels (~1400 MPa).

Here is some temperature dependent stress-strain data for typical steels. You'll also find grade 50 steel on the site.
