Hi,

I have modeled a two phase unit cell with one inclusion in a soft matrix. I have applied appropriate periodic boundary conditions. Load is applied a displacement. I have solved the problem using FEA through ABAQUS. Now I want macroscopic stress-strain response of the material.

What I have done is, taken the Reaction force and divided it by the area and similary displacement and didvided by length, will this give me the stress-strain response or do I have to use some homogenisation methods.

Thank You

Regards
