Abstract
Formation of dent defects in steel pipelines is not uncommon. A dent is a plastic deformation causing strains in the pipe wall which can be a threat to the structural integrity of the pipeline. This study investigated the effect of dent shapes, dent depths, and internal pressures on the strain distribution of the pipe. The work was completed using full-scale tests and numerical method. The study found that as the D/t ratio and the pressure increases so does the maximum strain around the dent. The study found that the location of the maximum strain value does not change with D/t ratio or internal pressure for rectangular dents. The maximum strain occurs at 125 mm away from the dent centre and at the dent centre for the longitudinal and circumferential axes, respectively. For spherical dent the location of the maximum strain in the longitudinal and circumferential axes differs for different pressures.
