It was shown that primitive loops could be used to create extended dislocations via superposition; as in the local continuum model for dislocations. It was noted that displacements due to these force arrays had to be calculated by using an appropriate form of the Green's function for anisotropic materials. Self-energy and interaction energies of the extended defects could be calculated. It was also possible to construct models for kinks and jogs. The effects of crystal structure upon the interaction energies with point defects could be calculated. This approach provided a rapid means for assessing the effects of elastic anisotropy and crystal structure upon the properties of crystal defects.
