Dear Prof. Taylor,
Thank you for your response. I tried what you mentioned and the results are identical. However, I faced something which I cannot perceive. When I fictitiously increase the size of RVE (even 1 million times larger than the size of my macro problem), I obtain the exact same results as a very small RVE. Could it be due the homogeneous behavior of the RVE? If yes, could you please point out the theoretical reason behind that?
Thanks in advanced.
