Crushable Foam Plasticity Model (Abaqus)

[shaldar]

Hi, I am a new user of Abaqus (using v6.10). I am trying to implement Crushable Foam Plasticity Model. People have used it, however, I could not use this model. I have uniaxial compressive test data from which others have implemented the model.
Can anyone please help! What am I doing wrong!
I can not insert picture, otherwise I could show my input and experimental data.

Helps are a lot appreciated.

Regards,
