Abstract
Corrosion is one of the most important damage mechanisms for ship structures and a significant portion of the maintenance budget is directed toward corrosion-related problems. A major challenge associated with the assessment of the impact of corrosion on the integrity of engineering structures is the quantification of the amount and severity of the corrosion damage that is present in those structures. Corrosion defects are typically characterized by random spatial distributions and variabilities in sizes, shapes, and morphological characteristics throughout the exposed part of the structure. For ship structures in particular, current corrosion pit survey practices are largely based on a visual assessment of the state of corrosion, making the assessment of the impact of corrosion a highly qualitative process that is also very susceptible to error. The present work has been motivated by the desire to provide a realistic and systematic framework for utilizing data collected during ship structural surveys to assess the probabilistic residual strength of corroded ship structural panels.
