... ABSTRACT Corroded pipes are increasingly repaired with composite material because of its low cost, simple and quick process. However, the repair effect will be affected by factors such as long time loads, seawater immersion and so on. This paper studies the effect of prolonged seawater...

... ABSTRACT Local buckling and plastic collapse of corroded pipes has been r/investigated, for cost-effective and safe design of pipelines and risers. The analytical equations derived by the author in 1998 are newly extended to account for the effect of yield anisotropy. This study is motivated...

... Pipes YOII Bai and S@ren Hauch J P Kenny A/S Stavanger, Norway ABSTRACT Buckling and collapse strength of corroded pipes has been investigated, for cost-effective and safe design of pipelines and risers. Two sets of analytical equations are newly proposed for collapse capacity of corroded pipes...

... of Wrinkling in Corroded Pipe Daniel P. Nicolella and Marina Q. Smith Southwest Research Institute San Antonio, TX, USA ABSTRACT This paper describes a full scale testing and finite element investigation of the wrinkling behavior of corroded pipe. It is applicable to corroded pipe subjected to multi-axial...
