Shear Modulus G12 of a Unidirectional Composite
Shear Modulus G12 of a Unidirectional Composite
(OP)
I believe I am getting myself confused and seeking clarification.
Lets say I have a unidirectional carbon fiber laminate. From testing, I have E11 and the E22 properties. I am looking to get G12, say for an FEA model. Since I have a composite material it's not isotropi, so the isotropic formula for G = E/2(1+poissons) is not valid. I have to use the Huber's equation of the orthotropic case: G12 = sqrt(E1*E2)/2*(1+sqrt(poissons12*poissons21)).... Is that correct?
OR is there another way to get G12 of a transversely orthopedic material that I am missing??
