Abstract

Eshelby’s equivalent inclusion method (EIM) were used to address the inhomogeneous inclusion problem while considering the effects of the intrinsic eigenstrain. The interaction energy between screw/edge dislocations and inhomogeneous inclusions were explicitly derived. To validate the model, the results of dislocation-void interactions were compared with the results of molecular dynamics (MD) simulations. The model’s capacity were fully evaluated and the effects of inclusion parameters were discussed, including the intrinsic eigenstrain and elastic constant.

Key words： eigenstrain; dislocation; inhomogeneous inclusion; Eshelby’s equivalent inclusion method (EIM)
