Representative Volume Element and Fiber Geometry

While a composite as the whole thing is a rather complicated structure, the essential relations may be illustrated by means of a small but representative 

Remark 5.1. K representative volume element is the smallest region of the composite over which mechanical as well as electrostatic fields are macroscop-ically uniform. 

The essential statement about the composition of the considered composite is provided by the fiber volume fraction v. As the material distribution does not
