Assessment of stress intensity factors for cast iron pipes with pitting corrosion

Accurate prediction of structural response of buried metal pipes relies upon the surrounding soil condition as well as pipe wall thickness deterioration. The presence of localized pitting corrosion, which is induced due to the electro-chemical reaction between soil and iron, has been identified as one of the main deterioration mechanism of pipe wall thickness. These corroded pipes, when exposed to severe loadings, can be easily subjected to...
