Tensor Based Finite Element Model for the Calculation of Leakage Field in Magnetic Flux Leakage Testing [PDF]

, 2020
Magnetic flux leakage (MFL) testing is a widely used electromagnetic nondestructive testing (ENDT) method, which has the ability to detect both surface and sub-surface defects in conductive materials. One of its best features is its ability to mathematically model field leakage from the defect area in a magnetized material. In this paper, we propose an
