Material to replicate biological tissue

Hi,

I am trying to find a suitable material to replicate some biological materials in laboratory experiments. The tissue is a layer that forms part of the porcine abdominal wall. We have data on the tensile mechanical properties of the tissue under uniaxial and equi-force biaxial testing.

I have attached stress stretch curves for the material in uniaxial and equi-force biaxial tensile loading. I am looking for a thin material that best matches these properties.

Thanks
