Hi, I'm an italian student of University of Roma Tre, in Rome. I need help to realize a quick model of an oesophageal stent with an auxetic geometry. I already realized the geometry, but I need help to define the materials of the model. I need the value (even a mean value or an aproximation) of some mechanical constants (I'm realizing a linear model)

- Young's Modulus
- Poisson's Ratio
- Density
- Initial Yield Stress
- Isotropic Tangent Modulus

For some organic materials:

- Oesophageal Mucosa + Submucosa
- Oesophageal Muscle (I know that Oesophagus has two layers of muscles but I don't want an accurate model)
- Tunica Adventitia

Thanks to everybody that will help me!
