Thermo-elastic analysis of edge dislocation using extended finite element method

In the present work, the extended finite element method (XFEM) is successfully implemented for the thermo-elastic analysis of edge dislocations. Volterra type edge dislocation is modeled using Heaviside and core enrichment functions. The singularity at the dislocation core is captured through infinite domain solution at the core. The Peach-Koehler force is numerically evaluated using the domain form of the J-integral from the XFEM solution of...
