Plastic Strain Data for Steel and PTFE

Plastic Strain Data for Steel and PTFE

Plastic Strain Data for Steel and PTFE

(OP)
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
 

RE: Plastic Strain Data for Steel and PTFE

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

RE: Plastic Strain Data for Steel and PTFE

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).
