Modeling honeycomb in Comsol

I am trying to model an aluminum honeycomb core in a structural mechanics model in Comsol 4.2. I'm stuck in trying to define the orthotropic honeycomb material as completely as Comsol requires, since the manufacturer's data only provides the E33 stiffness (given as the compressive modulus) and the G13 and G23 shear moduli. I am not sure how to go about finding the rest of the independent material properties (E22 E33 G12 and poisson ratios v12 v13 v23) to populate the stiffness (E), poisson's (nu), and shear (G) vectors in the material definition. I've searched around a bit and read that one can make reasonable approximations for the missing properties as percentages of the given data, but I don't have the actual percentages. Any guidance you might have for me as a COMSOL neophyte would be much appreciated!
Thanks,
Joe
