Understanding the stress fields and energetics of dislocations is of fundamental importance towards comprehending material behaviour at a microscopic scale. In this investigation, sessile edge dislocations are simulated using Finite Element Method, by feeding in the appropriate stress free Eshlyby transformation strain in the model, corresponding to the introduction of an extra plane of atoms. Anisotropic conditions are taken into account in the simulation. The results of the simulation are compared with the standard equations from the theory of elasticity. Further, the energetics of interaction between the simulated dislocations is studied and compared with available analytical results.
