419 軟質介在物近傍の転位構造(OS3-3 構成式(1))(OS3 機械材料の変形とそのモデリング)  [in Japanese] 419 Dislocation structure at a plastically-deformable inclusion  [in Japanese]

We numerically analyze slip deformation in models of dual phase materials that contains a plastically-deformable or plastically-non-deformable inclusion, and compare dislocation structures in the vicinity of each inclusions. The results show that the hardness of inclusion does not have large effect on the structure of dislocations outside the inclusion. On the other hand, distribution of normal stress in inclusion show large difference between the plastically-deformable inclusion model and the plastically-non-deformable inclusion model. We discuss the relationship between development of slip deformation and stress, distribution in inclusion.
