What are the formulae of Voigt, Reuss and Hill Poisson ratio in terms of independent elastic constants (C11, C12, C44) or in terms of bulk and shear moduli for cubic ? Whether they are same or different for all?
PR= (3B-2G) / (6B+2G).
I would like you to check this video based on Voigt and Reuss Notation in real world composite application

There is huge pressure of getting good impact factor on scholars now a days. On the other hand Taxonomy is a very dry subject and the concerned papers can only get citation in same group of organism.
