a multi-linear curve material

[alirezacivil]

Hi,
How I can define a multi-linear curve uniaxial material, similar to "MultiLinear Material" but with different unloading stiffness and features?

you cannot modify the unloading characteristics of that model using input arguments. You either have to use an alternative material or code something up.

Thanks for your response.

I wanted to use Hysteretic Material for this purpose but apparently this material is not working in this version of opensees.
Do you have other suggestions for the alternative material?
If not can you please introduce some references for coding a new material?

Thanks a lot.

what do you mean not working? have you tried it?
