Hi all,
I understand that the Krenchel orientation factor can be used to modify the Rule of Mixtures to help account for the loss of properties during non-axial loading.
The Halpin-Tsai equation however, doesn’t have any term related to the angle of loading. Can the Krenchel factor be used to modify the Hapin-Tsai equation, and if so where in the equation does it go?
If not, how does Halpin-Tsai account for any changes in loading angle? Is it just accounted for empirically in the ‘eta’ term?
I’ve been asked to plot modulus as calculated using Halpin-Tsai for a number of load angles 
.
Many thanks for any help!
