Hello All
I need to model a material in Abaqus that when I load the piece, the
material behaves with an Elastic modulus and when I unload the piece the
material behaves with a different Elastic modulus but don't recover all
the strain when the stress is released.
Enclosed you can find the behavior that I want to model.
Any ideas??
Thanks in advance.

That's an interesting
That's an interesting problem. There may be a material model that can do this, but I have no idea which one. An alternative is to load the piece, then import the results into a new analysis with a different material applied and then unload it. I'm pretty sure you can import the deformation and strains but change the material in that way, but not 100%.

Pseudo-elasticity
I think such a material model is called "pseudo-elastic". Googling "Pseudo-elasticity" + "Abaqus" seems to yield many papers - Good luck!
