| 中文摘要 | The speckle-interferometry technique (SPI) was used to investigate the influence of anodic current on bulk deformation in the plastic zone at crack tip of corrosion Fatigue by comparing the crack tip opening displacements of pure copper specimens in air and in 3.5% NaCl solution. In order to distinguish the different influences of anodic current on the bulk deformation and the surface deformation al crack tip, comparative analyses have been made by measuring the surface strain distributions near crack tip. After applying anodic current, both the plastic zone size and the strain on the surface ahead of crack tip increased significantly. The results indicated that the anodic current has no obvious influence on the deformation of internal material in the plastic zone at crack tip: anodic dissolution can release surface strain hardening and enhance the crack tip surface deformation but it cannot influence the mechanical behavior of internal material in the crack tip plastic zone directly.
