Modeling and Analysis of a Free Spanning Pipeline With Randomly Distributed Corrosion
Some corrosion defects will appear outside the aged submarine pipelines due to the corrosive sea environment. These defects can depress the strength and integration of the pipeline systems. This paper establishes a novel model using finite element method to describe the corroded pipelines with rando...
