Description
Summary:•Tensile stress is evaluated from magnetic Barkhausen noise energy hysteresis loops.•Coercivity is the most sensitive tensile stress indicator.•A simulation tool is developed to link Barkhausen noise and internal stress.•An ideal Barkhausen noise sensor orientation for stress evaluation is predicted. The analysis of the magnetic Barkhausen noise energy hysteresis cycles, MBNenergy(H), is a promising non-destructive testing method for evaluating internal mechanical stresses in ferromagnetic structural steels. This study applies this method to two ferromagnetic materials with significantly different behaviors subjected to uniaxial tensile stress. Coercivity is shown to be the most sensitive tensile stress indicator. A multiscale model is then developed to simulate the stress-dependent MBNenergy(H) anhysteretic behavior. Combined with a hysteresis contribution, it successfully reproduces the whole cycle. 2D simulation predictions reveal that the identification of uniaxial tensile stress is more efficient when the magnetic field is applied with an angle between 30° and 75° from the stress direction. The proposed modeling approach allows the prior determination of the most favorable configurations for the sensor orientation depending on the material tested and all available a priori knowledge of the stress configuration.
