Stress Field of Dislocations

The dislocations are associated with elastic stress fields around them. This stress field is crucial for the dislocation to interact with other dislocations and crystal defects. For a straight edge and screw dislocation in an isotropic medium, the stress/strain field analysis is quite straightforward. However, it becomes compli­cated with the elastic anisotropy of the crystal and other variations in dislocation characteristics.
