2.1.2 Transversely isotropic fiber

The Edit page for a transversely isotropic fiber looks like this:

Here A,T means Axial (along) the fiber, and Transversal (radial) direction of the fiber, respectively. For TI materials, you need 5 moduli, 2 CTE values, and 2 values for each transport property (if you are going to use them; otherwise enter zero). a/b is not used with TI fibers because a/b is used only with Halpin-Tsai micromechanics formulas, which are valid only when using isotropic fibers.
