Analysis of failure initiation in corroded cast iron pipes under cyclic loading due to formation of through-wall cracks

The major factors contributing for the longitudinal failures in large-diameter cast iron water pipes are identified as corrosion and internal water pressure. Evidence of deteriorating pipeline integrity due to fluctuations of internal pressure loading was reported. This study aims to investigate the fatigue resistance of cast iron pipes and to identify the pipes in a water network that are at high risks of fatigue damage. Stress-controlled...
