| The plastic deformation at the crack tip in a crystal is analyzed that caused the dislocation sliding along the light sliding planes by the joint action of the thermal fluctuations and the shear stress. Various crack shapes are studied: the crack-cut, the wedge-shape crack, the parabolic crack and others. The numeral analysis is carried out for a crystal of a-Fe. |
