Detection of Mechanical Damage Using the Magnetic Flux Leakage Technique [PDF]
2004 International Pipeline Conference, Volumes 1, 2, and 3, 2004 Since magnetism is strongly stress dependent, Magnetic Flux Leakage (MFL) inspection tools have the potential to locate and characterize mechanical damage in pipelines. However, MFL application to mechanical damage detection faces hurdles which make signal interpretation problematic: 1) the MFL signal is a superposition of geometrical and stress ...

Magnetic Flux Leakage Course of Inner Defects and Its Detectable Depth [PDF]
Chinese Journal of Mechanical Engineering, 2021 AbstractAs a promising non-destructive testing (NDT) method, magnetic flux leakage (MFL) testing has been widely used for steel structure inspection. However, MFL testing still faces a great challenge to detect inner defects. Existing MFL course researches mainly focus on surface-breaking defects while that of inner defects is overlooked. In the paper,

Damage identification of broken wires inside and outside the wire rope
Gong-kuang zidonghua, 2021 The wire rope broken wire damage detection is mainly focused on the outside broken wire damage detection, not on the inside broken wire damage detection. Moreover, the inside and outside broken wire identification accuracy is not high.
