The magnetic Barkhausen noise energy hysteresis cycles, MBNenergy(H), were evaluated as a nondestructive testing characterization method to identify intern mechanical stress in ferromagnetic parts. Oriented grains electrical steel, and iron-cobalt specimens were tested as model materials of opposite behaviors. Tensile stress tests were run and revealed MBNenergy(H) coercivity as the most correlated indicator. In parallel, a predictive multiscale model was developed to simulate the stress-dependent MBNenergy(H) anhysteretic curves. A hysteresis contribution was added, and the resulting hysteresis predictions were validated by comparison to the tensile-stress experimental tests. 2D simulation predictions reveal the identification of uniaxial tensile stress as more efficient when the magnetic field is applied within an angle between 30° and 75° from the stress direction. The simulation method allows the foresee of the most favorable sensor orientation configurations depending on the material tested and all available a priori knowledge of the stress configuration.
