Material from xy data
Material from xy data
(OP)
Hello...
First of all...sorry for my bad english!!
It's possibile to create a new material from ?-? data?
Thanks!!

RE: Material from xy data
thanks!!
RE: Material from xy data
if that the case. then yes.
but ensure that abaqus use engineering stress and log strain
RE: Material from xy data
And how I can insert and use the data?

RE: Material from xy data
*MATERIAL
*PLASTIC
stress_1,strain_1
stress_2,strain_2
...
where the pairs (stress_i,strain_i) define the material's curve.
RE: Material from xy data
Stress is true stress, not nominal stress. This is covered fairly well in the docs.
To expand on EricCabrol's post;
*material, name=...
..
*plastic
200,0
210,0.01
220,0.02
230,0.05
...
Where 200 MPa is the yield stress. The data pairs then describe the material curve post-yield.

If it is material steel. If you do not have Stress Vs strain curve, using Ramberg–Osgood material behaviour is a good starting point with yield stress and tensile strength.
