Assessment of Interaction Between a Dent and an Adjacent Corrosion Feature on Pipelines and the Effect on Pipeline Failure Pressure by Finite-Element Modeling

Dents and corrosion are two types of defects commonly found on pipelines. Although major efforts have been made to assess the defects of each type, there is a limited understanding of interaction between the two defects in adjacency. In this work, a finite-element (FE) model was developed, enabling assessment of the interaction between a dent and an adjacent corrosion feature and prediction of failure pressure of the pipelines. Results showed...
