Optical Analysis of Ductile Fracture of Metals

  • F. P. Chiang
  • S. Li


The optical technique capable of recording 3-D deformation is applied to different cracked aluminum alloy specimens under tension. The experimental results are compared with the theories at the corresponding deformation stages. The singularity forms agree well with HRR field for stationary cracks and agree with the solutions proposed by Gao and Hwang when crack grows.
