Limits of the plastic material model
Limits of the plastic material model
(OP)
hi, i read the documentation on this but could not get a definite answer out of it (though i believe to have read it somewhere):
For this model to work i need to supply pairs of yield stress/plastic strain points that lead to a stress strain curve that has an decreasing gradient after its elastic section, right? Else it will fail?

RE: Limits of the plastic material model
400.0, 0.0 (while 400.0 is the yield stress)
410.0, 0.05
415.0, 0.1
...
Otherwise I think Abaqus issues an error message.
RE: Limits of the plastic material model
thank you for your answer.
This was not what i was asking:
I asked, whether Abaqus' ordinary plastic material model needs a yield stress/strain table whos graph has a decreasing inclination (as metals usually have in their plastic region)
