BWBN material model

Hi everyone

I want to consider stiffness and strength degradation as well as pinching effects. For this aim, I want to use Bouc–Wen model but there are not parameters that consider pinching effects ($q $zetas $p $Shi $deltaShi $lambda) in Bouc–Wen model, so I have to use BWBN model but I have another problem with BWBN model, there are not parameters that control material degradation ($deltaNu $deltaEta) in BWBN model. Is it possible to model stiffness and strength degradation with BWBN material?

Thanks so much
