Process Compression test data into ANSYS

[AnPham]

Hi,

I have experimental data of a compressed test with Stress-Strain graph like shown below.
In linear elastic region, Stress/Strain do not equal Young modulus.
How can I use this data and reproduce the experiment in ansys./

Thank you,

But Young modulus is determined by Stress/Strain in linear elastic region.

Yes, but in that grap, linear elastic region, relationship between Stress-Strain is not Linear, which is the curve. I dont understand it

It says 'cell walls bend', are you working on some sort of honeycomb structure?

I want to perform this problem:
