Hello everyone,

I am working on simulation of bone scaffold structures which are porous structures. I am trying to mimic the simple compression experiment test of scaffold structure via simulations.

When I plot my stress strain graph, the graph I am getting depicts the materials properties (getting same elastic modulus, yield strength as the specified material) but not the structural properties. The elastic modulus, yield strength, etc. of porous structure is different from the solid structure while doing experimental tests.

Can you please guide me which part I am missing in the simulations?

Thank you in advance

Best regards.
