主 题:inhomogeneity edge dislocation singular integral equation stress intensity factors
摘 要:The elastic interaction of the mode Ⅰ plane crack with an interracial crack along a circular inhomogeneity is dealt with. The dislocation density and the stress intensity factors (SIFs) of the mode I plane crack are obtained numerically. A new kind of dislocation equilibrium equation about the plane crack is applied. The influence of some material parameters on the dislocation density and SIFs are analyzed.
