Combined hardening plasticity

Hello all
I want to model a process and I need to use the combined hardening model.
My question is how to insert the flow curve and combined hardening data(used for unloading) to the Abaqus. In detail I can ask :
1. I have to insert a flow curve (yield stress vs equivalent plastic strain) as a material behaviour independent of hardening behaviour of material (independent from isotropic or kinematic hardening)Where should I insert this flow curve? (tabular data (yield stress,equivalent plastic strain))

2. I need to specify the unloading behaviour of the material at different strains. How can I insert the data. I need more information than what is mentioned in the "
I have a stabilised cyclic curves, how can I convert it to tabular data? Also is it possible to use different cyclic curves?

Thank
