The near tip stress and deformation fields were analyzed, and the results compared with two-dimensional plane stress solutions. A double shear band was found ahead of the crack tip which created a three-dimensional zone extending several sheet thicknesses before the crack. This mechanism leads to an irregular blunt tip shape at the midplane of the sheet. Distinct differences in crack tip shape and the deformation fields were found between the perfect plasticity solution and the strain hardening solution. The analysis was also compared with experimental results obtained by other investigators.
