Traditional investigation of polyethylene pipe (PE) subjected to external loads focused only on the study of mechanical behavior or the failure judgment, but could not predict the damage evolution process. In this paper, a quantitative assessment was

Dent is a common geometric deformation defect on oil and gas pipelines. Compared with plain dent, composite dent has a greater impact on the pipe’s load-bearing capacity. There are great differences in the evaluation methods about dent under differ
