Sh. Munsonmcgee et Rl. Mccullough, ORIENTATION PARAMETERS FOR THE SPECIFICATION OF EFFECTIVE PROPERTIES OF HETEROGENEOUS MATERIALS, Polymer engineering and science, 34(4), 1994, pp. 361-370
A general formulation is presented for the orientation averaging of th
e properties of representative volume elements of heterogeneous materi
als. Approximations are introduced that result in the identification o
f four independent orientation parameters that are required to specify
a general state of three-dimensional orientation. The general relatio
nships are reduced further for the special case of ''planar'' and ''ax
ial'' distribution and applied to an aggregate averaging scheme for sh
ort-fiber composites.
