[en] It has been found in experiment that the local-scale pit corrosion of aluminum alloy 7075-T6
can lead to dramatic loss of its macroscopic tensile ductility. Based on the Gurson’s void model, the present paper aims to investigate quantitatively the changing characteristics of the plastic property and ultimate strength for the aluminum alloy with skin-deep pit corrosion. The tensile behaviors of the corroded 7075-T6 specimens with the different degrees of pit corrosion and weight loss are estimated by micromechanical analysis in this paper, and also the yielding strengths of the specimens are evaluated by the Gurson’s criterion. The predicted properties of the corroded specimens are in accordance with the experimental results very well.
