How to obtain stress strain curve in Abaqus?
How to obtain stress strain curve in Abaqus?
(OP)
Hello,
I am performing an analysis to predict the overall properties of composite material(fibers and Matrix, 3D). I have got the desired properties of the material. Now I would like to get the stress vs strain curve to know the behavior of the material. How do I proceed?
Thanks in advance.
Comments are welcome

1. Apply a displacement to 1 face and report out the total reaction force divided by the cross-sectional area.
2. Apply a pressure to 1 face and report out the displacement.
I hope this helps.

Thanks for your suggestions. I have already used the second approach. I would like to get the load vs displacement curve. My interest is to get the load vs displacement upto the elastic limit of the composite material. I also have applied plastic material inputs to the model. When I go to the X-Y DATA manager-create- ODB FIELD OUTPUT, I will then have to select unique nodal in the POSITION TYPE and then pressure and displacement below. In the ELEMENT/NODES tab, if I select NODE SETS, I don't get any option?
How do I proceed?
Thanks..

As an aside, what are hoping to gain from a stress-strain curve if you already have properties to assign to your model?

For that how do I constrain the face on which I apply pressure loading? I was thinking of modeling a rigid plate(analytical rigid)on the surface of loading. I have several issues in modeling the rigid plate too.
So how do I go ahead to obtain the load displacement curve?
