Processing of a Hrtem Image Pattern to Analyze an Edge Dislocation
Dislocations were introduced in the theory of Elasticity to evaluate the possibility of multiple values in displacement fields. The initial work was done by Volterra  in the 1900’s who came with the basic types of dislocations that currently are used in theoretical elasticity. The argument was further elaborated by Love  in the 1920’s. In the 1930’s, dislocations re-appeared as an argument to explain the actual behavior of crystals upon deformations compared to theoretical results coming from crystalline structures [3, 4, 5]. In the 1960’s, using X-rays dislocations were visualized by reconstructing X-ray diffraction patterns. However, no efforts were made to numerically or analytically evaluate the observed patterns.
