In the synthesis of crystalline materials the atomic structure of crystalline systems are not found to be ideal. They exhibit, for example, to a variety of forms of defects such as point‐ or line‐defects, impurities, grain boundaries, pop‐ins, and cracks. In this paper a truncation‐interpolation model of the structural properties of defects is considered for the general case for line‐defects, namely, the mixed‐dislocation. In this work an analysis of the dislocation density is undertaken, in particular, in the limit of the core where the dislocation core becomes important. One feature of this analysis is to explore a modification of the traditional classical field theory of dislocations. The modification presented here was invoked as a scheme to investigate the dislocation density of the mixed dislocations in nanostructures which remains ill‐defined in the traditional classical field theory of dislocations. Starting from a quasi‐analytical classical field theory our modelling method is referred back to another scheme that determines the dislocation density starting from experimental observations from high‐resolution transmission electron microscopy.
