I am so excited learning how to model hyperelastic materials. But I still need some better understanding how to correctly model in Abaqus. 

I am modeling rubber material using ogden parameters in Abaqus. I obtained Ogden parameters from test data until strain of 200%. I assumed the hysteresis suboption parameters as 1, 1, 0.05, and 0. Abaqus results shows good hysteresis loop until shear strain of 130%. After that, only the shear stress S12 increased and shear-strain E12 remains 130%. I confirmed displacement is increasing but strain E12 does not. Similar results when I used Yeoh model.

Does anyone know if there is an additional option to include in my modeling?. I appreciate your comments.
