利用 Eshelby 等效夹杂法 (equivalent inclusion method, EIM) 处理非均匀夹杂. 考虑了固有本征应变的影响, 显式地推导出了不同种类位错与非均匀夹杂的相互作用能. 以空洞为例, 将所得结果与分子动力学 (molecular dynamics, MD) 模拟计算值进行了比较, 验证了模型的有效性. 充分讨论了模型的应用范围, 并系统比较了夹杂本征应变与弹性常数对位错-夹杂体系反应能的影响.

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.
