how to set up a Parallel model between BWBN model and hardening model?

[luochuizi]

as the topic,i want to set up a Parallel model in my research.as we know BWBN model can't simulate Isotropic hardening.but hardening can get it.
i met this problem in my research,but i have no ideal to set up a Parallel model.they are two different materials,and i want they work at the same
element and direction to build my twonodelink element.
wish for help!
here are the code of the materials and element.
node 1 0.0 0.0 ;
node 2 0.0 0.0;
fix 1 1 1 1 ;
uniaxialMaterial BWBN 1 0.0417 116.47 1.007 0.5 0.5 1 0.88 0.95 0.003 0.04 0.00001 4.81644E-07 0.001 1000;
