Fracture experiments reveal variations in material strength from defects in aluminum plates, suggesting implications for corrosion analysis.
Fracture experiments were performed on thin 2024 aluminum plates with different sizes and orientations of small holes and pits to mechanically simulate localized corrosion and to examine the strength degradation of this material under static uniaxial tensile loading conditions. Crack initiation locations and stress distribution were evaluated by using the boundary integral equation method. The results showed some interesting variations in material strength depending on the spatial distribution and size of the small defects. This paper presents the preliminary results of an ongoing study on the characterization of the degradation of structural materials due to corrosion and fatigue.
