We will consider the acoustic birefringence with ultrasonic detection and its application in slightly anisotropic polymers for residual stress characterization.
In 2014 Jiapei Dai [1] reported evidence of anisotropic Brownian motion, and in 2015 Felix Scholkmann [3] detected a sidereal time dependence, indicative of a process driving the preferred Brownian motion diffusion direction to a star-based preferred direction.
a) It should have good agreement with experimental rock strength values; (b) it can be expressed mathematically by simple equations; and (c) it should have the possibility of being extended to deal with anisotropic nature of rock failure.
However, for the anisotropic diffusion problem we consider here, in the case of strong non-grid aligned anisotropies, an exhaustive search leads to the best overall results for the low-caliber interpolation, and therefore we use this strategy in our numerical experiments.

The lipid composition of the cell membranes is diverse across the membrane, and that produce anisotropic lateral condensation of these lipids to condensed- regions and fluid-regions [1].
Because it is extremely flexible and easy to implement, they say, it is an essential tool in modeling inhomogeneous, anisotropic, and dispersive media with random, multilayers, and periodic fundamental or device nanostructures.
This phenomenon is described and simulated by Dafalias using a simple theory of plasticity [10], which combines Hill's quadratic yield criterion for orthotropic sheet metals with the concept of plastic spin as an essential constitutive component for the orientational evolution of the anisotropic tensorial internal variables [11].
The initial stress state of the natural deposited ground is anisotropic in the sense that the vertical stress is typically larger than the lateral stresses.
The approach incorporates an anisotropic adhesive interface between the backing and adhesive layers.
In general, the ground is an anisotropic medium whose thermal conductivity depends on the direction.
