Hello,
I would like to model a material that has a higher yield strain in compression than in tension. The linear region has the same modulus for both tension and compression. Post yield I wish to use kinematic hardening.
Could anyone tell me what is the best material model to use for this.
The models listed seem to assume the failure strain in compression and tension is the same....
Could anyone help?
Thanks
