Effect of location of crack in dent on burst pressure of pipeline with combined dent and crack defects

Burst pressure of pipelines with longitudinal cracks located at the centre of rectangular dents varies with defect size and recent reports indicate that it could be very high for shallow cracks inside shallow dents and for cracks inside restrained dents. However, it is not clear whether cracks located in the flank of dents would have the same impact on burst pressure of pipelines with dent-crack defects. In addition, studies show that the...
