【 摘 要 】

The plastic deformation evolution at the crack tip in ?-Fe crystal under the condition of the plane deformation (modes I, II) is calculated. Temporal distributions for the plastic deformation, effective shear stress, stress intensity factor are derived. The calculation results for the blunt and acute crack tips are compared.
