Hi,
These days I am trying to understand a specific equation in the great article "Stephen W. Tsai, Jose Daniel D. Melo, An invariant-based theory of composites, 2014".
The link to the article: https://core.ac.uk/download/pdf/82317096.pdf
If someone know what is the meaning of equation 6 in the article and can share his knowledge I would glad to discuss about it and maybe things will be clarified.

Thanks a lot,
Itay. 

What is exactly your problem with the equation? The equation itself should not be that hard. And the vocabulary is described in the text above.

Hi oekmont, 
ThaTh for your repling to my question, I highly appreciate it.
To the best of my understanding, the numerator is accepted from the compliance matrix [a], by 1/(a11*h). I am still don't know how to calculate the denuminator.

Can you help me with that please?
I would glad to hear clearly explanation.
