Toward using the Villari effect for non-destructive evaluation of steel structures

This work follows on from studies carried out by Jiles and Atherton magnetic hysteresis the magnetomechanical effect. The Jiles–Atherton equation, which models rate of change magnetization with respect to stress, was solved numerically in forward reverse directions for stress up 90 MPa, suggesting that stressing carbon steel will cause a lasting sample. confirmed experimentally measuring B-field proximity samples C45 while undergoing tensile pattern domains reorient themselves geomagnetic field when loosens their pinning. A further experiment two confirms this, around showing strong changes according orientation at time stressing. has relevance non-destructive testing structures such as pipelines, experiments this is considered, well future prospects.
