 note = {On the basis of shock wave theory one of the author derived that the micro-crack nucleation is caused by the jump of the velocity along the intersected crossing line between two different stationary discontinuity bands characterized by vanishing velocity of an acceleration wave. In the previous paper, to consider dependence of the progress of ductile fracture of crystal solids on crystal orientations, the algorithm of acoustic tensors derived from the proposed model was built into finite element crystal plasticity model (FEPM) and the progress of ductile fracture in FCC bi-crystal was analyzed. In particular, the role of the crystal orientation and the grain boundary in the trigger of the transcrystalline fracture or intercrystalline fracture was examined. In this paper, the role of the crystal orientation and the grain-boundary triple junction in the trigger of the ductile fracture is studied and then the correlation between the progress of the ductile fracture and the amount of the jog caused by intersected cross slides of the dislocation slips is examined from the viewpoint of deformation controlled and/or diffusion controlled processes.},
