Triaxial Nonlocal Models and Applications
In the preceding section we discussed the most basic issues of the nonlocal models based on simple uniaxial cases. Now we address various other possible phenomenological formulations with features that are essentially three-dimensional, and show the general aspects of some practical applications. We also address the most basic problem of making an experimental determination of the characteristic length £.
