The Effect of Corrosion Patch Geometry on Stress Intensity Factors for External Surface Cracks in Cast Iron Water Mains

Stress intensity factors play a vital role in predicting the failures of cast iron water mains which are being utilised as buried water mains since several decades in many countries including Australia. The corrosion patterns which can vary from uniform, pitting and/or patch, may result uneven pipe thickness affecting the prediction of stress intensity factors. An inaccurate prediction of stress intensity of the corroded pipes can lead to false...
