Fiinite element analysis on multi-plane defects of ASTM 106 steel pipe

The predictions of pipeline burst pressure in the early stage are very important as the failure of pipelines can result in damage to the environment, injury to the public and high repair costs. Therefore, the accurate detection and characterization of defects in pipelines are of high interest, in pa...
