In many works, it was tacitly assumed that Hill's [11] suggestion of having the orthotropic directions aligned with the principal plastic stretch directions is valid, and this is indeed the case when loading maintains fixed principal stress directions from the onset of plastic deformation.

In the case of isothermal flow, a profile of principal stress difference from the surface to the core shows a V-shape, so molecular orientation is directly related to fountain flow (9).

Because the reservoir extends normal to the minimum principal stress direction in theory, it was expected that hydraulic fracturing creates the reservoir extending horizontally.

Many result quantities from finite element analysis contain directionality as well as value, and, in fact, there is an inherent directionality in most analysis data such as principal stress and deformation.
