Abstract
Nonlinear anisotropic materials were used to simulate the local effects of tensile stress concentrations on magnetic flux leakage (MFL) signals using three-dimensional finite element analysis (FEA). FEA was used to calculate the effects of near- or far-side pit depth and line-pressure induced simulated bulk tensile stress on radial MFL signals for pipelines with corrosion pits. It was found that the percentage changes increased with increasing degrees of anisotropy, simulating increasing stress concentrations, and also with greater far- or near-side pit depth for the three types of corrosion pit geometries studied.
