Exact solutions of near crack line fields for mode I crack under plane stress condition in an elastic-perfectly plastic solid
The near crack line analysis has been presented. The reasonable solution of the plastic stresses near the crack line region has been established. By matching the plastic stresses with the exact elastic stresses at the elastic-plastic boundary, the plastic stresses, the length of the plastic zone and the unit normal vector of the elastic-plastic boundary near the crack line region have been obtained for a mode I crack under uniaxial tension, as well as for a mode I crack under biaxial tension.
