Study on Mechanical Property of Corroded Pipeline

Abstract

Stochastic finite element method (FEM) was applied to analyze the mechanical property of the corroded pipeline. Firstly, mechanical properties of the corroded steel were studied. Then, dynamic properties of the corroded pipeline were investigated; sensitivity analyses were performed on the effective factors respectively. Considering the distribution characters of the defects on the pipe surface as stochastic variables, a series of numerical investigations were executed on the corroded pipeline. Relation between the dynamic property of the submarine pipeline and the corrosion state of the material is achieved.
