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 ...

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.
